Out-survive the wild in Survival School, read the clues the past left behind as a History Detective, and discover your own town runs on math in Math Around Town.
STEM · Survival School
8 modules · 4 weeks each
A year framed as 'how things survive and win': races and crashes, an invisible-power lab, a creature's whole life and its inherited toolkit, an animal-vs-animal showdown, a deep-time crime scene of fossils, a globe-trotting climate hunt, and a disaster-readiness mission to close the year.
STEMModule 1
Crash Lab
Roll two toy cars at each other and — BAM — one stops, one spins, both go flying. Speed one up and the crash changes completely. Why? This month you run a real crash lab: you'll smash, race, and roll things on purpose to learn what speeds them up, stops them, and steers them, then build a 'safe-stop' ramp that protects a fragile passenger when it slams into the wall.
The Week-4 Challenge
As crash-test engineers protecting a fragile passenger (an egg or a marshmallow rider), design and build a ramp-and-barrier 'safe-stop' that lets the cart roll fast but keeps the passenger unharmed when it hits the wall. Measure each run, compare two barrier designs, and fair-test the winner in front of a family audience. Points back to the opening BAM: now you control the crash.
STEMModule 2
Baby Pictures
Here's a baby photo of a frog — and it's a fish with no legs. Here's a baby butterfly — and it's a fat green caterpillar. Here's a baby you — and you look a lot like your parents, but not exactly. Every living thing has a wild before-and-after, and a hidden toolkit it got from its parents. This month you'll uncover the whole life story of a creature and prove where its traits came from.
The Week-4 Challenge
As family-tree scientists presenting to relatives, build a 'Traits Detective' report on one living thing (a pet, a plant variety, yourself and your family): chart its life-cycle stages, sort which traits were inherited and which were shaped by environment, and use evidence to argue your case. Share it with the very family it's about. Pays off the 'baby pictures' hook: prove where each trait came from.
STEMModule 3
Invisible Power
There's a force in your house right now that can move things without touching them, lift a paperclip into the air, and make your hair stand straight up — and you can't see any of it. This month you turn into an invisible-power scientist: you'll bend the no-touch force to your will, measure how far it reaches, and build a machine that does a real job using a power you can never actually see.
The Week-4 Challenge
As gadget engineers solving a real annoyance, define a small problem a magnet could fix (a key that always gets lost, a cabinet that won't stay shut, a paperclip sorter) and design, build, and fair-test a magnet-powered solution that meets your criteria. Compare two designs and improve the weaker spots. Delivers the invisible-power promise: a real machine run by a force you'll never see.
STEMModule 4
Clash of the Critters
Put a wolf, a lone tiger, and a swarm of ants in the same forest with one winter coming. Who makes it to spring? It's not always the biggest or the fastest — sometimes it's the one that teams up, or the one whose body just fits the place. This month you run the ultimate survival showdown, figuring out who wins where and why, then crown a champion built for one tough habitat.
The Week-4 Challenge
As nature referees crowning a champion for a real habitat, stage a 'Clash of the Critters' bracket: research several animals, use evidence to argue who survives well, who struggles, and who can't make it in one habitat — and whether going solo or in a group is the winning strategy. Crown and defend your champion to a family 'judging panel.' Settles the wolf-vs-ants showdown from day one with evidence.
STEMModule 5
The Edge to Win
Two moths rest on a tree. A bird eats the pale one and misses the dark one — and just like that, dark moths take over the forest. One small difference, and everything changes. This month you'll run games where a tiny trait decides who survives, collect the data yourself, and design the creature with the perfect edge to win in a world that's out to eat it.
The Week-4 Challenge
As trait scientists presenting at a science fair, design and run a fair survival game (a camouflage hunt, a beak-and-food race) where one variation gives an edge, graph who survived across rounds, and use your data to engineer the 'perfect edge' creature for a named danger. Defend the winning trait with your numbers. Pays off the moth story: your own data names the survivor.
STEMModule 6
Buried Clues
Deep in a desert with no water for a hundred miles, scientists dig up a whale. A whole whale, turned to stone, in the middle of the sand. How? This month you crack a deep-time crime scene: every fossil is a clue someone left millions of years ago, and you'll read those clues to figure out what lived here, what the place used to be, and what made it all disappear.
The Week-4 Challenge
As fossil detectives cracking a case for a museum, excavate a dig you built, read the fossil clues to reconstruct the ancient environment, and use evidence to explain what changed and why those plants and animals no longer live there. Deliver a 'case closed' museum exhibit or dig report to a family or co-op audience. Solves the desert-whale mystery from day one: the clues tell the story.
STEMModule 7
Around the World in a Backpack
You're going on a trip — but you can only pack one bag, and you don't know if you're headed somewhere freezing, soaking, or scorching. How do you know what to pack for a place you've never been? Because climate follows rules. This month you become a climate spy: track the weather where you live, then crack the climate code of any place on Earth and pack the perfect bag.
The Week-4 Challenge
As travel guides for a family heading somewhere far, log and graph two weeks of your local weather, then research and chart a contrasting world climate region. Build a 'pack-the-perfect-bag' guide that compares your home season to the destination using your tables and graphs, and justify every item. Pays off the one-bag challenge: the climate code tells you what to pack.
STEMModule 8
Disaster Squad
A hurricane is forecast to hit a town in three days, and you're on the squad that has to get it ready. You can't cancel the storm — but you can fix the roof, build the wall, and raise the house before it lands. This month you train as a disaster engineer: study how the wildest weather wrecks things, then design, build, and storm-test a real protection that saves the day.
The Week-4 Challenge
As a disaster-readiness squad protecting a community in a storm's path, pick a real weather hazard, compare at least two protection designs, then build and fair-test a model that reduces the damage — a flood levee, a windbreak, stilts, a wildfire gap. Fix the failure points and present your tested, evidence-backed solution to a 'town council' audience. Delivers the three-days-to-go mission: prove it saves the day.
Humanities · History Detectives
8 modules · 4 weeks each
An inquiry-forward year where the student is a history detective: every module opens with a real artifact, ruin, map, or primary source and the question 'how do we know?' The kid reads nonfiction for main idea and evidence, sequences events, builds claims from sources, and reasons about the past — investigating Roman ruins, a Viking ship burial, the deep history of the first Americans, and the documents of the colonies — toward a curated museum exhibit of their own local history.
HumanitiesModule 1
How Do We Know? The Detective's Toolkit
Here's a worn coin, a broken pot, and a faded letter — and from just these three things, a real detective can tell you who lived here a thousand years ago, what they ate, and what they believed. People who solve the past are called historians and archaeologists, and they read clues the way you read a book. This month you'll learn their toolkit on a real mystery object, and earn your detective's badge for the year.
The Week-4 Challenge
As a newly badged history detective, run a 'mystery object' investigation: examine a real or pictured artifact (or a 'time capsule' object from home), record what you observe, then make and defend a claim about who used it and why — labeling each idea as fact, clue, or guess. Present your case to a family 'review board.' Earns the badge promised in the opening: you can now read a clue and build a claim.
HumanitiesModule 2
Buried in Time: The Secrets of Rome
One day in the year 79, a mountain called Vesuvius exploded and buried an entire Roman city — Pompeii — under ash in a single afternoon. Frozen in time were loaves of bread, painted walls, even people's pets. Centuries later, diggers found it all. This month you become a Roman archaeologist: you'll read what the ruins reveal about how Romans really lived, and reconstruct a day in Pompeii from the clues in the ground.
The Week-4 Challenge
As an archaeologist of Pompeii, reconstruct one scene of Roman daily life entirely from real artifact evidence: pick a room, a street, or a meal, gather what the ruins reveal, and build a labeled reconstruction with a short report explaining what each clue proves. Present it as a museum 'dig findings' display to family or co-op. Digs straight out of the buried-city opening: the clues rebuild the day.
HumanitiesModule 3
Roads, Walls & Water: The Engineers of Rome
The Romans built roads so straight and so strong that some are still walked today — two thousand years later. They moved rivers across whole valleys on stone bridges to bring water to their cities, and they did it without a single machine with an engine. How? This month you'll map the Roman world, follow a road and an aqueduct across it, and crack the case of how a city of a million people kept itself fed and watered.
The Week-4 Challenge
As a Roman infrastructure investigator, map and explain one Roman system — a road, an aqueduct, or the layout of a city — using a real map and the language of cause and effect. Build a route map plus a short explainer of how it worked and why it went where it did, and present your 'how Rome worked' case to an audience. Follows the straight-road opening: trace the system, then explain the why.
HumanitiesModule 4
The Viking Ship Burial
Diggers in Norway once uncovered a whole Viking ship buried in the earth — and inside it, a powerful person laid to rest with weapons, jewelry, even horses, ready for a journey to the next world. Add carved stones covered in a secret alphabet called runes, and you've got the ultimate cold case. This month you'll excavate the real evidence of who the Vikings were — not the cartoon raiders, but the traders, sailors, and farmers the artifacts reveal.
The Week-4 Challenge
As a Viking-age archaeologist, build an evidence case that answers 'who were the Vikings, really?' Gather at least three kinds of artifact clue (a burial, a trade good, a runestone), explain what each proves, and write a claim that corrects one myth about Vikings using your evidence. Present your 'case file' to family or co-op. Cracks the ship-burial opening: the artifacts, not the cartoons, tell the truth.
HumanitiesModule 5
The First Americans: Reading the Land
Stand on a giant earthen mound shaped like a coiled snake, longer than three football fields, built by hand a thousand years ago — by people whose names we're still learning. Across this land, the first Americans left mounds, tools, art, and trails that tell of huge cities and clever ways of living, long before any European arrived. This month you'll read the land and the artifacts to uncover the deep, real history of the first peoples of this continent.
The Week-4 Challenge
As an investigator of early America, research one Native nation or culture from before European arrival and build an evidence-based profile: where they lived (a map), how the land shaped their life, and what their artifacts and structures reveal — pulled from real sources and written as an informative report. Present your findings to a family or co-op audience. Reads the snake-mound opening: the land and its objects tell the deep story.
HumanitiesModule 6
Whose Story Gets Told?
For a long time, the history of the first Americans was written mostly by people who weren't them — and a lot got left out or got it wrong. But Native nations are still here today, telling their own stories in their own words. This month you'll compare what different sources say about the same people and event, learn to spot whose voice is missing, and practice the detective's hardest skill: deciding which source to trust.
The Week-4 Challenge
As a fair-minded historian, take one event or topic about the first Americans and compare how two different sources describe it — noting who wrote each and what each leaves out. Build a claim about which is more trustworthy and why, and propose how to tell the story more fairly. Present your 'whose story' case to family or co-op. Answers the missing-voices opening: weigh the sources, then make it fair.
HumanitiesModule 7
Case Files of the Thirteen Colonies
A real letter, written by hand four hundred years ago, complains that the new colony is starving and that no one will work. Another, from a different colony, describes the first Thanksgiving feast. These aren't from a textbook — they're the actual words of the people who were there, and they don't always agree. This month you'll read the real documents of the thirteen colonies and learn to tell a firsthand account from a story told later.
The Week-4 Challenge
As a colonial document detective, investigate one colony using at least two real (or faithfully adapted) primary sources, sort firsthand from secondhand, and write up what the evidence shows about life there — including where the sources disagree. Present your 'case file' to a family or co-op audience. Opens the starving-colony letter: read the real words, then judge what they prove.
HumanitiesModule 8
Your History Museum
All year you've cracked cases across two thousand years — Rome, the Vikings, the first Americans, the colonies. Now real historians do the final job: they build a museum so others can see the evidence too. This month you'll become a curator and investigate the history right under your feet — your own town, street, or family — then build a real exhibit and open its doors to visitors.
The Week-4 Challenge
As a museum curator, research a piece of real local history — your town, neighborhood, school, or family's past — using real sources (interviews, photos, records, a local site), then design and build an exhibit with labels, evidence, and a clear claim about what happened and why it matters. Host an opening for family, co-op, or neighbors. Closes the year: the detective who earned a badge in Module 1 now curates the evidence for the public.
Math · Math Around Town
8 modules · 4 weeks each
A year spent running the math behind a small town: stock the market and size up a crowd, slice the bakery's pies into fair shares, crack the locksmith's missing-number codes, lay out the park and the playground, run the clock and the scale at the corner store, call fair games at the arcade, design the town's house numbers and price tags — and finish by opening your own booth at the town fair. Daily skill practice is aligned to Khan Academy Grade 3 math — each four-week module wraps the current unit in the year’s mission.
MathModule 1
Stocking the Market
The town market opens Saturday and the shelves are empty — you're in charge of stocking them. How many apples fit in a crate? How many crates fill the truck? You can't count every apple before the doors open, so you'll learn the grocer's trick: chunk one box, multiply up, and round to a number you can trust. By the end you'll size up a whole truckload in your head and never come up short on opening day.
The Week-4 Challenge
As the market's stock manager, plan the opening-day order: pick several products, estimate how many you'll need by chunking-and-multiplying and rounding, and explain the too-low and too-high bounds so the owner trusts your numbers. Present your stocking plan to the 'owner' (a family member) and defend why your guess won't leave shelves empty or overflowing. Loops back to the empty-shelves hook with a real order.
MathModule 2
The Bakery's Fair Slice
The town bakery has one rule: every slice is a fair slice. But a customer swears your half is smaller than her half — and now you have to prove it isn't. This month you run the bakery counter, cutting pies and cakes into fair shares and proving it with a number line. The twist: 1/2, 2/4, and 3/6 can all be the very same slice. By the end you can win any 'my piece is smaller!' argument with math.
The Week-4 Challenge
As the bakery's fair-slice keeper, design and prove fair cuts of a real (or paper) pie, cake, or pan of treats: show the same amount written several ways on a number line, and settle a customer's 'my slice is smaller!' complaint with a diagram. Present your ruling to a family 'customer.' Ties back to the unhappy customer in the hook — now you prove the slice is fair.
MathModule 3
The Locksmith's Code
A safe at the town locksmith's shop is locked with a missing number: 6 × ? = 48 opens it. Crack the code and the safe swings open. This month you're the locksmith's apprentice, and every lock hides a missing number you find two ways — by sharing into equal groups, or by asking 'what times what?' The faster you know your facts, the faster the locks fall. By the end you crack 8 × ? = 56 like you've got the key.
The Week-4 Challenge
As the locksmith's apprentice, build a set of 'number locks' — real missing-number puzzles (share the coins into equal pouches, pack the parts into equal boxes) — solve each by both sharing and grouping, and show the fact-family ring of keys that opens it. Present your hardest lock and walk a grown-up through cracking it. Loops back to the 6 × ? = 48 safe — now you open it on sight.
MathModule 4
Laying Out the Park
The town wants a new park, and you're the one drawing the plan. How much grass to cover the playing field? How much fence to wrap the whole edge? You'll find out by tiling the field in squares and walking its border — no giant tape measure needed. This month you lay out paths, fields, and flower beds, sorting each shape by its rules. By the end you can plan a real space and tell the builders exactly how much they need.
The Week-4 Challenge
As the park planner, design a small park or playground on grid paper: tile each area to find how much grass or surface it needs, walk the borders to find the fencing, and label every shape by its attributes. Present a labeled plan to the 'town council' (the family) and explain why area and perimeter aren't the same order. Ties back to the grass-and-fence hook with a buildable plan.
MathModule 5
The Corner Store Clock & Scale
You're running the corner store, and two things rule the place: the clock and the scale. A customer needs to know if the bread's still warm (baked 23 minutes ago) and exactly how heavy their bag of apples is. This month you tell time to the minute, weigh in grams and kilograms, and pour drinks by the liter. By the end you can answer 'how long ago?' and 'how much does it weigh?' for any customer who walks in.
The Week-4 Challenge
As the corner-store keeper, run a measurement shift: time how long tasks or 'bakes' take to the minute, weigh several products in grams or kilograms, measure liquids in liters, and solve a real one-step customer problem ('how many minutes since it was baked?', 'which bag is heavier and by how much?'). Present your shift log. Loops back to the warm-bread-and-heavy-apples hook with exact answers.
MathModule 6
The Arcade's Fair Game
The town arcade has a game everyone says is rigged — and the owner hired YOU to find out. Is the ring toss really winnable, or does it cheat? The only way to know is to play it a bunch and chart what happens. This month you become the arcade's fairness inspector: run games, tally results, build a bar graph, and read it to answer 'how many more?' and 'is it fair?' By the end you can prove with a graph whether a game gives players a real shot.
The Week-4 Challenge
As the arcade's fairness inspector, pick or invent a game, play it enough times to gather real data, chart the results in a scaled bar or picture graph, and use the graph to rule whether the game is fair (and answer 'how many more wins?' from it). Present your verdict with the graph as evidence to the 'owner.' Ties back to the rigged-game hook — now you decide it with data, not a hunch.
MathModule 7
Numbering the Town
The town is adding a new street and every house needs a number, every shop a price tag. But what's the biggest number you can make from the digits 4, 0, and 7 — and which house gets it? Move the digits and 407 becomes 740 becomes 470, all different addresses. This month you're the town's number-maker: place value tells you what each digit is worth, you add and subtract within 1000, and you multiply by tens to set prices fast. By the end you can build, add, and break apart any number up to a thousand.
The Week-4 Challenge
As the town's number-maker, design the new street's house numbers and a shop's price list: use place value to build and order numbers, add and subtract within 1000 to total an order, and multiply by tens to set prices. Present your numbering plan and walk a grown-up through one tricky total, showing how place value made it fast. Loops back to the 4-0-7 address hook — now you assign every number on purpose.
MathModule 8
The Town Fair Booth
It's the biggest day of the year — the Town Fair — and you've earned a booth. All year you stocked shelves, sliced fair, cracked codes, laid out the park, ran the clock, and called fair games. Now you build one exhibit that uses your math to pull in a crowd. Pick the math you love most, make something a visitor can actually try, and prove your numbers are right. By the end you've turned a whole year of town math into a booth people line up for.
The Week-4 Challenge
As a Town Fair exhibitor, design and run one booth that combines at least two of the year's big ideas (estimation, fractions, measurement, data, place value) into an interactive exhibit a visitor can try — a stocking guess-jar, a fair-slice station, a measure-and-win challenge, a fair-game predictor. Show your math is correct and present to real fair visitors. The year's capstone: turn the town's math into something people experience.
Grade 4 · Ages 9-10
The year they start building
Design, test, and improve real machines in The Engineer’s Year, travel the medieval world through its greatest stories in The Storyteller’s Atlas, and run a city zoo & aquarium on Wild Numbers.
STEM · The Engineer's Year
8 modules · 4 weeks each
One spine — the engineering-design loop (define → imagine → plan → build → test → improve) — established with tangible structures (bridges, towers) and then applied across every grade-4 science domain (energy, light, sound, life, Earth), so the student spends the whole year being an engineer-scientist. Every module ends in a hands-on Week-4 Challenge; Module 8 is the year's capstone that reuses everything.
STEMModule 1
Building Bridges
A good bridge holds trucks, trains, and crowds — far more than it weighs all by itself. How? The secret isn't just strong materials. It's smart shapes. Crack that secret and you stop being someone who walks over bridges and start being someone who could build one.
The Week-4 Challenge
As a structural engineer, design → build → test → improve a model bridge for a real community need, then write it up and present it. Weeks 1-3 hand over the forces, the build skill, and problem-framing; Week 4 runs the full process end to end with a written proposal + presentation.
STEMModule 2
Tower Power
The tallest building on Earth is over half a mile high — yet it doesn't tip, bend, or blow over. How? You already cracked how bridges span across; now you'll crack how towers reach UP. By the end you'll engineer the tallest, strongest tower you can.
The Week-4 Challenge
As a structural engineer, design → build → test the tallest tower you can that holds a load on top and survives a wind test, then present it. Weeks 1-3 hand over stability (no tipping), the tall-and-strong build skill, and bracing against wind; Week 4 builds and presents the full tower.
STEMModule 3
Chain Reaction
One tiny push at the top, and — clack-clack-CLACK — a marble races down a ramp, knocks a domino, flips a lever, and rings a bell across the room. You didn't touch any of that. So what carried your push all that way? Energy. By the end you'll build a chain reaction that passes energy through step after step to finish a job all by itself.
The Week-4 Challenge
Design → build → test → improve a multi-step chain reaction (a Rube-Goldberg machine) that transfers and converts energy through several steps to finish a task. Weeks 1-3 hand over energy-as-motion, transfer between steps, and form-to-form conversion.
STEMModule 4
Now You See It
Close your eyes. The room doesn't disappear — but you can't see it. Open them, and light floods in. Here's the secret: you never see an object directly. You only ever see the light that bounced off it and dove into your eye. Once you know that one rule, you can build a tool to see around a corner, throw a giant shadow on the wall, or catch a picture out of thin air.
The Week-4 Challenge
Design → build → test an optical device — a periscope (see over a wall), a pinhole viewer, or a shadow-puppet theater. Weeks 1-3 hand over straight-line light & shadows, mirrors & the bounce rule, and bending/pinhole tricks.
STEMModule 5
Good Vibrations
Put your hand on your throat and hum. Feel that buzz? That's a wave — your vibration pushing on the air, racing out to someone's ear. Every sound you have ever heard is a wave. And if you can make a wave on purpose — a long buzz, a short buzz — you can send a secret message across a room with nothing but a flashlight or a buzzer.
The Week-4 Challenge
Build a simple instrument AND design a coded signaling system to send a real message to a family member across a distance, then compare the two methods. Weeks 1-3 hand over sound-as-wave, pitch & loudness for the instrument, and patterns-as-code.
STEMModule 6
Nature's Engineers
A duck's foot is a built-in paddle. A cat's eye is a night-vision camera. A sticky burr that grabbed a dog's fur gave us Velcro. Every plant and animal is a walking toolkit of clever designs, tuned over millions of years to survive. Engineers steal nature's best ideas all the time — it's called biomimicry. This unit, so will you.
The Week-4 Challenge
Design & model a biomimicry invention inspired by a real structure or sense that solves a human problem, then explain the nature→design link. Weeks 1-3 hand over external structures, internal structures, and senses → brain → response.
STEMModule 7
Story in the Stone
A flat band of rock in a canyon wall is a page in Earth's diary. A fossil fish on a mountaintop means that peak was once the bottom of a sea. The ground under your feet has been built, worn down, and rebuilt a hundred times by water, ice, and wind — slowly enough that you'd never notice. But you can prove it with a tray of dirt and a cup of water.
The Week-4 Challenge
Build a model landscape, run a fair erosion test on it, record & graph the data, and map/explain how it changed (read its layers). Weeks 1-3 hand over reading rock layers, fossils as evidence, and the erosion test + map-reading skill.
STEMModule 8
Power the Planet
Flip a switch and a light comes on. But where did that energy begin — a lump of coal, a rushing river, the sun? Every choice has a price for the planet. And nature pushes back with floods, quakes, and wildfires. This is your final mission as a Grade-4 engineer: use everything you've learned all year to power people cleanly — and protect them when nature hits hard.
The Week-4 Challenge
The year's capstone: pick a real community problem and compare ≥2 solutions against criteria — power people with a renewable source OR reduce a natural hazard's impact — then build/model, test, and present, reusing the whole year's toolkit. Weeks 1-3 hand over the energy sources, a working renewable-capture device, and hazard-reduction.
Humanities · The Storyteller's Atlas
8 modules · 4 weeks each
A year-long 'Storyteller's Atlas' the student builds world by world: every month opens with a story — a legend, a voice, a quest, a folktale, a primary-source letter — then works outward to the real era, place, and culture that produced it. Each world adds a map page, a retold tale, and a 'how we know' page to the atlas, and the recurring move is finding the true story inside the story. The year closes with a civic capstone — because a citizen, too, is someone who tells their community's story and argues for its future.
HumanitiesModule 1
The Tale of the Sword in the Stone
A boy nobody noticed walks up to a sword stuck fast in a stone, gives it a tug, and pulls it free — and just like that he's king of all England. People have told that story for a thousand years. But here's the puzzle that opens your whole year: the castles and knights in it were REAL, and the king was NOT. This month you'll learn to read a legend AND read the real medieval world hiding inside it.
The Week-4 Challenge
The First Page of My Atlas: A Medieval Story-Map — a foldout that retells a short Arthurian or Robin Hood episode in the student's words, mapped onto a real medieval-Europe setting (castle, manor, village) with a 'real vs. legend' panel. Weeks 1-3 hand over character/setting in depth, theme, and legend-vs-history.
HumanitiesModule 2
Words the Heroes Left Behind
Have you ever called a hard job 'Herculean,' or a weak spot an 'Achilles' heel,' or someone a 'knight in shining armor'? You were quoting stories thousands of years old without knowing it. This month you become a word-detective: every saying you crack opens a door to the legend that made it — and by the end you'll have written a brand-new legend of your own, packed with sayings the future might quote.
The Week-4 Challenge
Write a Legend Worth Quoting — an original quest legend with a hero, a trial, and a lesson, ending in a memorable saying the student invents, plus a one-page 'word-origins' key explaining the allusions woven in. Weeks 1-3 hand over allusion/figurative language, point of view (1st vs. 3rd), and theme.
HumanitiesModule 3
The Librarian Who Saved the World's Stories
Imagine a library so important that scholars crossed deserts to reach it, where the world's smartest people raced to translate every book ever written before it was lost forever. That was the House of Wisdom in Baghdad — and it's the reason you can read at all in a world that nearly forgot how. This month you join the translators, and you'll meet a real traveler whose own diary is one of the best stories of the age.
The Week-4 Challenge
An Atlas Page for Baghdad: 'How We Know' — an exhibit page that integrates two sources about one House-of-Wisdom scholar or invention, with a sidebar comparing a firsthand traveler's diary to a secondhand history, plus a compass-and-ruler star pattern. Weeks 1-3 hand over main idea, integrating two texts (RI.4.9), and firsthand vs. secondhand (RI.4.6).
HumanitiesModule 4
The Storyteller Who Remembered an Empire
In West Africa there were people whose JOB was to remember everything — every king, every battle, every family's history — and carry it all in their heads, because nothing was written down. They were called griots, and one of their greatest tales is about a boy who couldn't walk until age seven and grew up to found an empire: Sundiata. This month you learn how a whole empire's story was kept alive by memory and voice alone — and you'll become a griot yourself.
The Week-4 Challenge
Become a Griot: The Telling and the Verdict — a recorded oral telling of a West African tale paired with an evidence-backed opinion ('Who should be remembered — Sundiata or Mansa Musa?'). Weeks 1-3 hand over the oral epic and theme, firsthand vs. secondhand accounts, and building a claim from evidence.
HumanitiesModule 5
Big Feelings in Tiny Poems: Tales from Japan
On the far side of the world lived a warrior who could split a falling leaf with his sword — and then sit down and capture an entire autumn in a poem of just seventeen syllables. He was a samurai, and his code was called bushido. This month you cross to the islands of medieval Japan, read its folktales and its three-line poems, compare its warrior-poets to the knights you met in the fall, and write poems and a tale of your own.
The Week-4 Challenge
A Japan Atlas Page: Poems, a Tale, and a Compare — the student's own haiku with brush-style art, a retold Japanese folktale, and a knights-vs-samurai compare page. Weeks 1-3 hand over the samurai/cross-cultural compare, haiku imagery & figurative language, and folktale theme/point of view.
HumanitiesModule 6
Can We Believe Marco Polo?
A young man from Venice came home after twenty-four years away and told the wildest travel stories anyone had heard: a road across the whole world, paper money, black stones that burned (coal), a Chinese emperor richer than any king. People called him 'Marco Millions' because they thought he was lying. This month you become the detective: you'll read his own words about the Silk Road and imperial China — and decide for yourself how much to believe.
The Week-4 Challenge
The Verdict on Marco Polo + an Invention's Journey — a 'believe it or not' page weighing his firsthand account against other sources, plus a researched presentation of one Chinese invention and a trader's travel journal. Weeks 1-3 hand over main idea & geography, integrating sources on the Four Great Inventions, and firsthand vs. secondhand credibility.
HumanitiesModule 7
The Argument That Made a Country
What would you do if a king an ocean away taxed your tea, your paper, even your playing cards — and you got no say at all? Two hundred and fifty years ago, thirteen colonies had that fight, and they didn't win it with muskets first — they won it with WORDS, in letters and speeches and one famous document. This month you'll read the very words real people wrote on every side, then take your own stand: stay loyal, or break away?
The Week-4 Challenge
Make Your Voice Heard — a persuasive pamphlet or speech as a Patriot OR a Loyalist, presented aloud, built on the year's ONE AI-coached essay ('Was breaking away the right story to tell? Should the colonies declare independence?'). Weeks 1-3 hand over reading primary sources & firsthand vs. secondhand, the two opposing points of view, and the synthesis essay.
HumanitiesModule 8
Write the Next Chapter: We the People
Winning a war was the easy part. Now thirteen quarreling states had to agree on the rules for a brand-new country — what the government CAN do, and the freedoms it can NEVER take away. They argued it out and wrote it down, and it began 'We the People.' Here's the twist that ends your year: that story isn't finished. The last chapter is yours to write — find a real problem where YOU live, and propose how to fix it, the way a citizen does.
The Week-4 Challenge
Be a Citizen: The Atlas's Last Page (year capstone) — identify a real problem in your home, neighborhood, or community; research it; build a claim; propose a solution with reasons and evidence; and present it, closing the year's Storyteller's Atlas with the student's own community. Weeks 1-3 hand over reading a founding document, claim-from-a-document, and researching a real problem.
Math · Wild Numbers
8 modules · 4 weeks each
The student is a junior keeper helping run a city zoo and aquarium, and every module is a real animal-care job that can't be done without the unit's math — counting a teeming colony, ordering tons of food, splitting fish among tanks, decoding an animal's number-pattern, sharing a meal fairly, building an enclosure to size, running the gift-shop register, and designing a brand-new exhibit to scale. Daily skill practice is aligned to Khan Academy Grade 4 math — each four-week module wraps the current unit in the year’s mission.
MathModule 1
How Many Animals?
Your first day as a junior keeper, and the head zookeeper hands you a wild question: how many animals live here? A single ant colony has 2,500,000 ants, the aquarium's krill tank holds 1,800,000 of them, and the oldest tortoise is older than your great-great-grandparents. Nobody counts that high — they READ it, using the secret code our number system uses for giant numbers. This month you'll crack that code, compare and round the zoo's biggest counts at a glance, and tell visitors the true size of the wildest collections.
The Week-4 Challenge
The Big-Numbers Zoo Sign — as a junior keeper, pick several real giant zoo/aquarium numbers (an ant colony's size, the krill in a tank, a tortoise's age, gallons in the shark pool), read and compare them, round each to a sensible size, and build an exhibit sign that makes those giant numbers understandable to a visitor who's never seen them.
MathModule 2
Feeding Time
It's Monday at the zoo and every animal is hungry: 14 penguins each eat 285 grams of fish a day — how much fish is that in all, and is there enough in the freezer? A keeper can't count fish one at a time; they reach for multiplication, the machine that scales a small amount up to a huge one fast. This month you'll run the feeding kitchen: order the food, scale the diets, and tell '6 times as much hay' apart from '6 kilograms more hay' before a single animal goes hungry.
The Week-4 Challenge
The Feeding Order — as the zoo's feeding-kitchen keeper, plan a real feeding day: decide how many kilograms of fish, hay, or fruit the animals need in all, use multi-digit multiplication (with area-model reasoning) to total it, and check the order with a rounded estimate before the food is bought.
MathModule 3
Into the Tanks
A delivery truck just dropped off 2,400 new fish for the aquarium, and you have to split them evenly across the tanks — but the count never divides perfectly, and those leftover fish need a home too. Every fish delivery, every new litter, every crate of gear gets divided into equal groups, and the leftover is never just a leftover. This month you stock the aquarium: divide the fish, the food crates, and the new arrivals into tanks and enclosures, and decide what every remainder really means.
The Week-4 Challenge
Stock the Tanks — as the aquarium's stocking keeper, take a real delivery count (fish, feed crates, or new animals), divide it into equal tanks or enclosures with place-value/area-model reasoning, and write the plan that says exactly what each remainder means in THAT situation (round up, drop it, or it's the answer) and why.
MathModule 4
Nature's Patterns
A cicada waits underground for exactly 13 or 17 years — never 12, never 16 — and then millions emerge at once. A sunflower's seeds spiral in a number pattern; a beehive's cells lock into a code. Numbers carry hidden structure, and a wildlife scientist reads it: which numbers split into neat factor pairs, which stubborn primes won't split at all, and which patterns follow a rule you can use to predict what comes next. This month you work the zoo's research lab: find the building blocks inside numbers and crack the codes that nature hides.
The Week-4 Challenge
The Pattern Field Guide — as a zoo research scientist, design a working number pattern or factor-based code drawn from real nature (a cicada cycle, a seed spiral, an animal marking): build it from real factor/prime structure or a stated rule, extend it, then reveal one hidden feature your rule creates that an outsider wouldn't expect — and challenge a partner to crack it.
MathModule 5
Fair Feedings
Two otters get their fish cut up differently — one meal split into 8 pieces, one into 12 — and now they're squabbling over who got the bigger share. In an animal kitchen, the same amount of food has lots of different names (4/8 of the fish is exactly 1/2 of it), and settling 'who got more?' keeps the animals happy. This month you run the diet kitchen: prove when two animals' shares are secretly equal and judge which of any two is bigger.
The Week-4 Challenge
Settle the Feeding — as the diet-kitchen keeper, take real cut foods or animal portions, use equivalent fractions to prove which shares are secretly equal, and use benchmark comparisons to settle every 'who got more?' dispute — then plate a demo that proves your calls.
MathModule 6
Building the Habitat
A new meerkat habitat needs building, and nothing comes out in whole numbers: a perch board is 3/4 of a meter, the burrow tunnel adds 1/2 a meter, and you have to mix 2/3 of a batch of sand times 3 to fill it. A real habitat builder adds and scales fractions, measures every piece to the nearest 1/4, then reads the whole job off a line plot. This month you put fractions to work: build an enclosure with them, combine them, and turn a pile of measurements into a picture.
The Week-4 Challenge
Build the Enclosure — as a habitat builder, plan a real enclosure piece or animal-food batch, use fraction addition/subtraction and multiplication to get every measurement right, measure your pieces to the nearest 1/2 or 1/4, and present a line plot of the measurements that proves the habitat fits.
MathModule 7
The Gift Shop
Two plush sea otters sit on the gift-shop shelf — one is $3.49, the other is $5.25 for a bigger one — and a visitor wants to know which is the better deal. The zoo's gift shop and snack cart run on decimals, and a decimal is nothing but a friendly fraction of 10 or 100. This month you run the register: read the price tags like a code, compare them by place value, and become the keeper who helps every visitor spend smart and never gets the change wrong.
The Week-4 Challenge
The Gift-Shop Price Guide — as the gift-shop keeper, compare real prices written as decimals, find the genuine better buy on several items, and build a small budget for a visitor's shopping run — justifying every choice with decimal place-value reasoning a customer could follow.
MathModule 8
Design a New Exhibit
The zoo director just handed you an empty lot and one job: design a brand-new animal exhibit that visitors and animals will both love. Real exhibit designers measure the world and turn it into numbers — converting units, finding area and perimeter for every habitat and path, measuring angles with a protractor, and using symmetry to make it look right. This month, for the year's grand finale, you become the zoo's exhibit designer and plan a real habitat, to scale.
The Week-4 Challenge
Design the Exhibit (YEAR CAPSTONE) — as the zoo's exhibit designer, plan a real animal habitat (an enclosure, an aviary, a tank, or a visitor path): convert units, compute area and perimeter for each zone, use measured angles and at least one line of symmetry, and present a labeled scale plan to the 'zoo director' with all the math shown.
Grade 5 · Ages 10-11
The year the stakes get real
Keep a crew alive with science in Survival Mission, stand inside history’s biggest moments in Eyewitness to History, and run the numbers that fly the mission in Mission Control.
STEM · Survival Mission
8 modules · 4 weeks each
The whole year is one survival expedition. The student is the science officer of a small crew that has to make it through real challenges — sort scarce supplies, ration without waste, grow food, recycle everything, find clean water, read the sky to navigate, and beat gravity to land safely. Each module is a survival problem that can only be solved by understanding the same grade-5 science, and the engineering-design loop is the crew's survival drill: define the danger, weigh the options, test it before lives depend on it, and fix what failed. The year builds toward designing a self-sustaining base.
STEMModule 1
Sorted for Survival
Your crew's supply crate got soaked and every label washed off. Now you've got bins of mystery powders, liquids, and solids — and you have to figure out which is drinkable, which is fuel, which is medicine, and which would hurt someone, WITHOUT a single label to read. Guessing could be deadly. This month you'll learn to read what something is made of from how it behaves — and build the field test kit that keeps your crew safe.
The Week-4 Challenge
Engineer a Survival Field Test Kit: design and build a set of property tests (float/sink, dissolve, magnet, conduct, react) and a sorting key that lets you correctly identify a tray of unknown 'supplies' your grown-up prepares. Run a crewmate (sibling/co-op partner) through your kit as the real-world test.
STEMModule 2
Ration Without Waste
Supplies are limited and there's no store for hundreds of miles, so your crew can't afford to lose a single gram. But cooking burns things, salt dissolves into nothing, fizzing tablets vanish into bubbles — is your stockpile actually shrinking, or just changing shape? This month you'll prove that nothing ever truly disappears, learn which changes you can undo and which you can't, and become the crew member who never wastes a thing.
The Week-4 Challenge
Run the crew's Waste-Nothing Lab: design fair tests for several survival 'transformations' (dissolving salt to recover it, a cooking change, a fizzing reaction), weigh and graph before/after to prove conservation of mass, and sort each into reversible (physical) or permanent (chemical). Brief your 'crew' (family/co-op) on which supplies they can recover.
STEMModule 3
Grow or Go Hungry
Your supplies will run out — the only way the crew survives long-term is to GROW food. But you've got barely any soil, so where will pounds of new tomatoes and beans even come from? Here's the wild part: plants make most of their bodies out of air and water, not dirt. Master that, and you can feed a crew from almost nothing. This month you'll engineer a growing system that turns sunlight, air, and water into food.
The Week-4 Challenge
Engineer a crew Food-Growing System: design, build, and fair-test a small grow setup (seedlings, a simple hydroponic jar, or a windowsill garden) by controlling ONE variable, and build a model showing how your plants turn air, water, and sunlight into food the crew can eat. Present your harvest plan to the 'crew' (family/co-op).
STEMModule 4
The Trash That Saves You
After a few weeks your crew has a pile of garbage — peels, scraps, dead leaves — and nowhere to dump it. On a real survival mission, trash is a death sentence... unless you have the secret weapon nature uses: a microscopic cleanup crew that EATS waste and turns it back into food for your plants. This month you'll harness rot itself, closing the loop so your crew's 'trash' becomes the soil that grows your next meal.
The Week-4 Challenge
Build the crew's Closed-Loop Recycler: set up and run a decomposition column or compost system, track it over the module, and model the full matter cycle that connects your trash → decomposers → soil → next crop. Teach the 'crew' (family/neighbors) how to close their own loop.
STEMModule 5
Find the Water
Your crew is down to one canteen and surrounded by water you can't drink — it's salty, muddy, or frozen solid. The planet is COVERED in water, yet the fresh, drinkable kind is a tiny hidden fraction. So where is it, how does it move from sea to sky to stream, and can you actually MAKE dirty water safe to drink? This month you'll map where Earth hides its fresh water and engineer a filter that could save your crew.
The Week-4 Challenge
Engineer the crew's Water Survival System: graph Earth's real water budget (salt vs. fresh, where it's stored) AND design, build, and fair-test a water filter / solar still that turns undrinkable water clear — defining your criteria and constraints, then iterating after each failure. Demo it to the 'crew' (family/co-op) who decide whether to trust it.
STEMModule 6
Don't Wreck the Base
Your crew has finally settled a base — but you almost ruined it. Dump waste in the stream and your drinking water turns toxic; clear too many trees and the soil washes away; foul the air and everyone gets sick. Everything you do to ONE part of your home touches all the others. This month you'll learn the hard way how connected Earth's systems are, study how real communities protect their resources, and write the rules that keep your base alive for good.
The Week-4 Challenge
Write the crew's Base Survival Code: investigate a real environmental problem and combine information from multiple real sources on how actual communities used science to protect a resource (water, soil, air, habitat), then draft an evidence-based set of rules and a recovery plan for your base, and present it to the 'crew council' (family/co-op/online audience).
STEMModule 7
No Compass, No Clock
Your devices are dead and you have to navigate — but you've got no compass, no clock, and no map app. The good news: the sky is a clock and a compass that never runs out of battery, if you know how to read it. A shadow tells the time and direction; the stars tell the season and the way; the Sun tells you where you are. This month you'll learn to read the sky the way every explorer in history did, and find your way using nothing but light.
The Week-4 Challenge
Build the crew's Sky Navigation Kit: collect your OWN multi-day data on shadow length/direction, daylight, and star positions, then build a working sun-clock/compass and a graphical display of the sky patterns that reveals time, direction, and season — and explain why the Sun outshines every other star. Teach the 'crew' (family/co-op) to navigate by sky.
STEMModule 8
The Drop Home
The mission's last step is the scariest: getting your crew (and one fragile cargo pod) safely back down to the ground. Gravity is pulling everything straight down, fast and unforgiving — drop something and it doesn't slow down on its own. Your whole survival now depends on engineering a way to beat the fall. This month you'll measure gravity's invisible grip and design a lander that brings precious cargo down soft enough to survive.
The Week-4 Challenge
Final Mission — the Safe-Landing Challenge: as crew engineer, define the design problem (land a fragile 'cargo' — an egg or marble — undamaged from a set height), generate and compare lander designs, run controlled fair tests, and iterate from every crash until it survives. Stage a live 'landing day' for the 'crew' (family/co-op) as the real audience.
Humanities · Eyewitness to History
8 modules · 4 weeks each
The student travels a deliberate sequence — the great American civilizations, the age when oceans connected the world, the Renaissance that reinvented seeing, samurai Japan, the rise of Russia, then home to the American West and the Civil War — and in each place reads and writes like a historian: weighing two accounts of one event, tracing point of view, quoting a source accurately, and turning evidence into a claim. Every era is taught through real texts — chronicles, letters, diaries, legends, treaties — so the skills ride on knowledge the student keeps.
HumanitiesModule 1
Cities of Stone: The Maya, Aztec & Inca
While Europe was deep in its Middle Ages, three American empires were building pyramids taller than ten houses, doing astronomy without telescopes, and running roads across mountains higher than the clouds — with no horses, no iron, and no wheels for carts. How? This month you'll read their own carved stories and a Spanish soldier's eyewitness account of a city he could barely believe, and write a guide to a wonder of the Americas.
The Week-4 Challenge
Write and design an illustrated 'Wonder of the Americas' field guide to one Maya, Aztec, or Inca achievement, drawing on at least two sources (one from the people themselves, one from outside) and quoting each accurately.
HumanitiesModule 2
When the Oceans Connected: The Age of Exploration
In 1492 the world's two halves had never met. Within a few lifetimes, potatoes were growing in Ireland, horses were thundering across the American plains, and ships were sailing right around the globe. One set of voyages rewired the whole planet — and the same voyages were a disaster for millions of people. This month you'll read sailors' logs and the words of those who met them, and argue what the Age of Exploration really cost and gained.
The Week-4 Challenge
Write an evidence-based opinion piece (with a counter-argument) taking and defending a position on whether a chosen explorer or voyage should be honored, citing at least three sources that disagree.
HumanitiesModule 3
A New Way of Seeing: The Renaissance & the Printing Press
About 80% of the people who visit the Louvre go for one small painting: the Mona Lisa. The man who painted her also sketched flying machines, dissected the human body, and designed cities — 500 years ago. At the very same time, a machine of metal letters was about to put more books in the world in 50 years than monks had copied by hand in a thousand. This month you'll meet the Renaissance and ask where genius — and big change — really comes from.
The Week-4 Challenge
Write an informative profile of a Renaissance figure or invention, then explain in a short claim how the printing press helped their ideas spread — drawing on multiple sources.
HumanitiesModule 4
Feudal Japan: Honor and the Sword
For 250 years one warrior class ruled Japan — bound by a code so strict that a single broken promise could cost a life, yet who also wrote delicate poems and held tea ceremonies. Three samurai generals dragged a country torn by war into a single, peaceful island. This month you'll step inside feudal Japan through its legends and laws, and tell a story where honor and survival pull a character two different ways.
The Week-4 Challenge
Write a short historical narrative set in feudal Japan in which a character faces a clash between loyalty and what's right, grounded in real details from the readings.
HumanitiesModule 5
Rivers of Power: The Rise of Russia
A land so vast it spans eleven time zones, so cold that armies have frozen trying to cross it — and it grew from a single trading town on a river into the largest country on Earth. How does a country get that big? This month you'll trace Russia's rise from river towns and onion-domed cities to the tsars who pulled a sprawling land together, reading the accounts of the people who lived it.
The Week-4 Challenge
Build an informative 'then and there' report on one slice of early Russian life (a trade city, a tsar, a winter, a fortress), integrating several sources and a map.
HumanitiesModule 6
Westward: Whose Land Was It?
Wagons rolling for two thousand miles. A poster promising free land. A railroad that suddenly let you cross the whole country in a week instead of half a year. To families heading west it looked like a dream — but the land wasn't empty, and the people already living on it saw the very same events as an invasion. This month you'll read both sides in their own words and argue: was America right to expand?
The Week-4 Challenge
Write an argument essay answering 'Was the United States right to expand westward?' using at least one settler source and one Native source, quoting each accurately and answering the other side.
HumanitiesModule 7
A House Divided: The Civil War
A country that wrote 'all men are created equal' kept four million people enslaved — and in 1861 it tore itself in half over it. The Civil War was the deadliest war in American history, and the people who lived it left us letters, diaries, photographs, and speeches that still speak. This month you'll read the voices of soldiers, the enslaved, and the freed, and uncover how a nation broke apart and tried to put itself back together.
The Week-4 Challenge
Write an evidence-based piece (informative report or argument) tracing one cause-and-effect thread of the Civil War — or a person's experience of it — through at least three primary sources, building a claim from the evidence.
HumanitiesModule 8
Telling the Whole Story: A Historian's Year
You've now read carved Maya glyphs, a sailor's log, da Vinci's notebooks, a samurai's code, a tsar's chronicle, two sides of the western frontier, and the letters of the Civil War. Here's the secret historians know: the past doesn't come with one true story — someone always has to choose what to tell, and how. This month you become that someone. Pick the moment from this year that still won't let you go, and tell its whole story your way.
The Week-4 Challenge
Choose any era or event from the year and produce a polished history piece — narrative, argument, or 'voices' collection — that draws on multiple sources, takes a clear point of view, quotes accurately, and is presented to a real audience.
Math · Mission Control
8 modules · 4 weeks each
A year as a flight analyst at Mission Control, running the numbers a real space program lives on. Every module is a mission job — logging instrument readings, computing fuel and mass, scaling a crew’s supplies, sizing a habitat, mapping a landing zone on a grid — and every deliverable goes to the flight team. Daily skill practice is aligned to https://www.khanacademy.org/math/cc-fifth-grade-math — each four-week module wraps the current unit in the year’s mission.
MathModule 1
Instrument Readings
Mission Control just lit up with sensor data: a temperature of 0.071 degrees, a pressure of 1.013, a distance of 2.305 kilometers. These readings run past the decimal point on purpose — a spacecraft's safety depends on reading the thousandths exactly. This month you decode instrument readings like a flight analyst and prove that one shift of the decimal scales the whole reading by ten.
The Week-4 Challenge
The Instrument Log: pick three real precision readings (temperatures, pressures, distances, masses), read and write each to thousandths in numerals, words, and expanded form, order them on a number line, and produce a clean flight-log reference panel — presented to a 'flight team' (family or co-op) who has to read it at a glance.
MathModule 2
Fuel and Margin
Launch needs 14.6 tons of fuel, the booster burns 3.85 on ascent, and you have a tank rated to 20 — is there enough margin to reach orbit? At Mission Control, adding and subtracting these decimals wrong isn't a bad grade, it's a scrubbed launch. This month you run fuel and mass numbers fast and exactly, and always check the margin makes sense.
The Week-4 Challenge
The Launch Budget: take a realistic mission resource (fuel, mass, power, water), list every amount as a decimal, total what's used, subtract from the limit to find the remaining margin, and present a go/no-go budget — to a 'flight director' (parent) — with an estimate shown beside the exact total as a sanity check.
MathModule 3
Supplies for the Whole Crew
It's no longer one astronaut — it's a crew of 36 on a long mission, and every one needs the full daily ration. Now you need 36 of everything, and 8,640 supply units to split into equal daily packs. Counting won't get you to launch; you need the multiplication and long-division machines that scale one crew member's needs to the whole roster and pack them fairly.
The Week-4 Challenge
The Crew Manifest: plan a realistic supply run for a multi-person, multi-day mission, use multi-digit multiplication to find every total needed, use long division to pack the totals into equal daily or per-crew kits, and present a one-page mission manifest showing the math — to a 'logistics officer' (parent/co-op leader) who must trust the totals.
MathModule 4
Per-Unit Burn Rates
The thrusters burn 0.6 of a unit of fuel per second and the descent lasts enough seconds to matter — and the life-support cartridge scrubs 0.25 of a liter of air per minute across an 8-hour shift. Get the decimal multiplication wrong and you misjudge the burn; get the division wrong and you misjudge how long the air lasts. This month you multiply and divide decimals to nail every rate.
The Week-4 Challenge
The Rate Sheet: pick a real mission rate (a fuel burn, an air-scrub rate, a data-downlink rate, a cost per unit), multiply to find the total over a long stretch and divide to find a per-second or per-unit figure, and publish a rate sheet a flight team could plan from — tested for accuracy with a worked check.
MathModule 5
Combining the Readings
Two crew members log water use in different ways — one in 2/3-liter scoops, one in 3/4-liter bottles — and you have to report the combined total to the flight director. The catch: thirds and fourths don't line up. This month you add and subtract fractions with different denominators so mismatched mission readings finally combine into one trustworthy number.
The Week-4 Challenge
The Combined Log: take real (or realistic) mission readings recorded in mixed fractions (water, time, sample mass), add them to find a total and subtract to find a remaining amount or a difference, then present an accurate combined report — handed to a 'flight director' (family member) who acts on the number.
MathModule 6
Scaling the Mission
Command cuts the mission to 2/3 its planned length, and a sample has to be split so each of several labs gets 1/4 of it. Shrinking a plan and sharing a sample both hit a strange-feeling truth: multiplying by a fraction makes things SMALLER, and dividing by a fraction can make them BIGGER. This month you use those rules to rescale a whole mission and fair-share a sample.
The Week-4 Challenge
The Rescaled Plan: take an original mission plan and produce a scaled version (2/3, 3/4, or 1/2) using fraction multiplication for every quantity and area, then divide a sample into equal unit-fraction shares for several labs, and present the rescaled plan beside the original — to a 'mission review' audience who checks the math.
MathModule 7
Sizing the Habitat
The crew needs a habitat module that encloses exactly the right cubic space for life support, the parts spec is in feet but the plan is in inches, and you must log sample masses to the nearest 1/8. How big does the module need to be? This month you compute volume, convert units without slipping a zero, and turn a stack of fraction measurements into a line plot that tells the mission's real story.
The Week-4 Challenge
The Habitat Spec: design a habitat module or storage bay, compute its volume (including a composite shape as additive volume), convert at least one measurement between units, measure a set of samples to the nearest 1/2, 1/4, or 1/8 and present a line plot of the data — delivered as a 'module spec' to a flight team that needs the right-size habitat.
MathModule 8
Mapping the Landing Zone
It's the mission's biggest call: pick and map a landing zone on a real coordinate grid, exact enough that the lander touches down where you say. You'll place every waypoint as an ordered pair, write the formula for fuel-to-target without solving it yet, name every region by its true shape family, and prove your map is precise. This is the month the whole year's math becomes one mission-ready map.
The Week-4 Challenge
Map the Landing Zone (year capstone): choose a real (or realistic) site, plot its key waypoints on a coordinate grid, classify the 2D regions by the shape hierarchy, write at least one numerical expression for a distance or fuel figure (and interpret it without solving), then present a labeled, to-scale mission map a flight team could use — to a 'mission review' panel of family or co-op.
Grade 6 · Ages 11-12
The year they think in systems
Take on real Cases, Crises & Controversies in STEM, decode the first civilizations at the Dig Site, and settle real arguments with numbers at The Data Desk.
STEM · Systems & Cycles
8 modules · 4 weeks each
Every module opens on a real, often contested case — a counterfeit, a collapse, a disaster, a controversy people are still arguing about — and the science is the tool the student uses to figure out what actually happened and what should be done. The student works as an investigator: reconstruct the event from the evidence, then take a defensible position on it.
STEMModule 1
The Counterfeit Catcher
A museum just paid millions for a 'priceless' painting — but a chemist proved it was a fake using a single chip of paint, because the pigment held an atom that wasn't invented yet when the artist supposedly lived. Every material is built from a specific set of particles arranged a specific way, and that arrangement is a fingerprint nobody can fake. This month you'll learn to read those fingerprints: model what materials are actually made of, test how they behave when you heat or cool them, and use it to catch counterfeits and tell look-alike substances apart.
The Week-4 Challenge
As an authentication lab, build particle models of several materials and run safe identification tests (density, melting/freezing behavior, solubility) to identify a set of 'unknown' household substances and expose a planted 'counterfeit', then present your evidence chain to a skeptical panel who decides whether your identification holds up. Make the reasoning public and challengeable.
STEMModule 2
The Energy Heist
Every bite of food you eat is stolen sunlight. The energy in a candy bar, a burger, a salad — all of it traces back to a plant that captured sunlight and locked it into sugar, and everything else just steals it down the line. Cut off the sunlight and the whole chain starves in days. This month you'll follow the heist: where the energy and matter in your body actually came from, and prove that the entire menu of life runs on a single original source.
The Week-4 Challenge
As food-system investigators, trace a real meal backwards to its solar source — modeling each matter-and-energy handoff — and reveal it to a public audience (a school, an online post, a family) as an 'energy receipt' for their food, complete with the evidence for why energy is lost at every step.
STEMModule 3
The Web Strikes Back
Someone released a few rabbits in Australia for hunting. Within decades there were billions — eating the land bare, collapsing farms, and changing the continent. No one planned that. This month you'll dig into real cases where one change to a food web exploded into something nobody predicted, work the actual population data, and model the hidden web of connections that turned a small decision into a continent-sized problem.
The Week-4 Challenge
As biosecurity analysts, model a real invasive-species or resource-collapse food web, analyze the population data, and present a 'what went wrong and what now' briefing to a mock agency panel or publish it for an online audience — with your evidence for the cascade front and center.
STEMModule 4
Last One Standing
The passenger pigeon was once the most numerous bird on Earth — flocks so huge they darkened the sky for days. In a single human lifetime, every last one was gone. Extinctions and collapses are still happening, and scientists fight hard over the causes: was it us, the climate, a disease, or all three at once? This month you'll take a real population crash, work the evidence, and argue the cause well enough to defend it against people who disagree.
The Week-4 Challenge
As expert witnesses, take a real extinction or population-crash case, build the data argument for what caused it, and defend your claim in a structured debate or published response against a peer arguing the opposing cause. Hold your position with evidence in front of a real audience.
STEMModule 5
When the Sky Turns
In 1900, a hurricane hit Galveston, Texas with no real warning and killed thousands — the deadliest disaster in U.S. history. We didn't yet understand how energy moves water and air around the planet. Weather is the water cycle and heat in violent motion, and reading it is the difference between a warning and a catastrophe. This month you'll model the engine behind storms, work real disaster data, and reconstruct what people could and couldn't have known before a real weather event hit.
The Week-4 Challenge
As disaster analysts, model the water-and-energy engine behind a real weather event (a named hurricane, flood, or heat wave), reconstruct the data trail leading up to it, and present a public 'what we knew, what we missed, what we'd do now' briefing to a community-preparedness audience.
STEMModule 6
The Ground Remembers
An earthquake can drop a coastline by several feet in seconds, and a fossil seabed sitting on a mountaintop proves the ground has been doing this for millions of years. Geologists can read a cliff face the way you'd read the rings of a tree — layer by layer, oldest at the bottom — and reconstruct disasters that happened long before any human was alive to record them. This month you'll learn to read the rock record and use it to reconstruct a real geologic event from the evidence it left behind.
The Week-4 Challenge
As forensic geologists, model the rock cycle and then read a real rock record (a famous cliff section, a local outcrop, a core sample dataset) to reconstruct and tell the story of a past geologic event, publishing it as a museum-style exhibit, trail interpretation, or online explainer for a public audience.
STEMModule 7
Poisoned Wells
In Flint, Michigan, a decision about water saved a little money and ended up poisoning a city's children with lead — and people knew the data and argued about it for over a year before anyone acted. Water carries whatever we put in it through the whole cycle, and deciding what level is 'safe' is a question of evidence and of justice. This month you'll trace a real contamination case through the water cycle, define with data what 'safe' actually means, and build the argument for who should have acted.
The Week-4 Challenge
As public-health investigators, trace a real water-contamination case through the water cycle, define data-based criteria for 'safe,' and present a 'what the evidence shows and who should have acted' case to a public board or online audience — taking and defending a position grounded in the numbers.
STEMModule 8
Build It Back Better
After a disaster — a flood, a contamination, an ecosystem collapse — someone has to decide how to rebuild, and the easy way usually recreates the same weakness. The whole year you've investigated systems that broke. This month you flip it: take one real failure you studied, define exactly what a fix has to do and what limits it, build a working model, test it with real data, and pitch your redesign to people who'll judge whether it would actually hold.
The Week-4 Challenge
As resilience engineers, choose a real failure from the year (a flood, a contaminated water source, a degraded ecosystem, a wasteful process), define measurable criteria and constraints, build and iteratively test a working model with data, and pitch your evidence-backed redesign to a panel, community group, or online audience who decides if it holds up.
Humanities · Dig Site
8 modules · 4 weeks each
A year spent as a junior archaeologist and source-detective, traveling down the great rivers in the order the cities actually rose: Mesopotamia, Egypt, the Indus, China, then Greece. Every module hands the student a real artifact or primary source nobody can just Google the meaning of — a clay tablet, a tomb wall, a stone law-code, an undeciphered seal, an oracle bone, a buried epic, a citizen's vote — and asks them to read it, weigh it against other evidence, and argue a claim about the people who left it. The arc moves from 'what even IS a civilization and how do we know anything about the dead?' through the five river valleys to a final week where the student curates and defends their own evidence-based exhibit. Argument writing and citing textual evidence are built straight into the detective work: a claim is only as good as the source behind it.
HumanitiesModule 1
Reading the Dead
A 5,000-year-old clay tablet sits in front of you, covered in wedge-shaped scratches. No one alive ever heard this language spoken. Yet scholars cracked it — and it turned out to be a receipt for beer. This month you become a source-detective: you'll learn how anyone knows ANYTHING about people who died before writing was invented, decode the world's first script, and prove a claim about the Sumerians using only the scraps they left behind.
The Week-4 Challenge
As a museum's junior research team, build an 'artifact case file' for a real Mesopotamian object (a cuneiform tablet, the Standard of Ur, a cylinder seal) and present it to an audience of family or co-op peers: state a claim about the people who made it, back it with at least three lines of evidence, and name honestly what the object cannot tell us.
HumanitiesModule 2
Inside the Tomb
Workers sealed a teenage king inside a stone room with everything he'd need for eternity, then hid the door so well it stayed lost for 3,000 years. When it was finally opened, the air still smelled of ancient perfume. This month you'll go inside the tomb — reading the painted walls, the buried objects, and the bodies themselves as evidence — to figure out what the Egyptians believed happened after you die, and why an entire civilization organized itself around the dead.
The Week-4 Challenge
As an exhibit designer for a 'Daily Life on the Nile' gallery, create a piece that uses real tomb evidence to teach an audience what ordinary Egyptians (not just pharaohs) believed and how they lived — and defend why your evidence supports it, distinguishing what the walls show from what they leave out.
HumanitiesModule 3
An Eye for an Eye
Carved into a black stone pillar taller than a grown adult are 282 laws written by a king named Hammurabi nearly 4,000 years ago — and some are brutal. Break a bone, lose a bone. Build a house that collapses and kills the owner's son, and your own son is put to death. This month you'll read the actual laws, put them on trial, and argue whether the world's first famous law-code delivered justice — or just protected the powerful.
The Week-4 Challenge
As a member of an ancient-law review panel, write and present an argument essay answering whether a chosen set of Hammurabi's laws was just, citing the laws themselves as evidence and addressing the strongest objection to your position — delivered to a panel (family/co-op) who hear both sides.
HumanitiesModule 4
The City That Vanished
Along a river in ancient India, archaeologists dug up cities with straight streets, indoor plumbing, and standardized bricks — built with engineering so advanced it shocked everyone — and then found the people simply… left. No grand tombs, no boastful kings, and a written script that to this day no one on Earth can read. This month you'll investigate one of history's great cold cases: who were the Indus Valley people, and why can't we crack their code?
The Week-4 Challenge
As a forensic-history team, build an evidence-based 'case for the Indus' — a profile of who these people were and a reasoned theory for why their cities were abandoned — that clearly separates what the evidence supports from what is speculation, for an audience of peers who pressure-test your reasoning.
HumanitiesModule 5
Bones, Bronze & the Long Road
A Chinese king 3,000 years ago wanted to know the future, so a priest carved a question into a turtle shell, held it to fire until it cracked, and read the answer in the breaks — and those scorched 'oracle bones' are the oldest Chinese writing we have. From those bones to a road of silk that stretched thousands of miles to Rome, this month you'll trace how ancient China invented, recorded, and traded its way into a civilization whose ideas still run through your daily life.
The Week-4 Challenge
As researchers for a 'Silk Road exchange' feature, produce a short multi-source research piece tracing one Chinese idea, invention, or good as it traveled — comparing at least two sources' accounts and assessing which is more credible — and present it to an online or co-op audience.
HumanitiesModule 6
The Song of the Hero
For 400 years, before Greece had an alphabet to write it down, blind poets recited from memory a 16,000-line story of a ten-year war, a wooden horse, and a hero who couldn't find his way home. People have argued ever since over a wild question: was any of it real? This month you'll read the oldest stories in Western literature, learn the hero's-journey pattern hidden inside them, and decide for yourself where the history ends and the legend begins.
The Week-4 Challenge
As a literary detective, create a piece that traces a Greek hero's journey through a real myth or a section of an epic AND takes a defended position on what the story reveals about Greek values — shared with an audience who reads or watches and responds.
HumanitiesModule 7
Who Gets to Decide
In one ancient Greek city, ordinary men dropped pebbles into jars to pass laws, picked leaders by lottery, and could vote to throw a too-powerful politician out of the country for ten years. They called it 'rule by the people.' But women, enslaved people, and foreigners — most of the city — got no say at all. This month you'll step into the world's first democracy, read what the Athenians actually argued, and decide: was this real freedom, or freedom for a lucky few?
The Week-4 Challenge
As a citizen of the ancient assembly OR a critic of it, write and deliver an argument (essay + speech) answering whether Athenian democracy deserves to be called free, citing Athenian sources and addressing the counterclaim — presented to a deliberating panel of peers or family who then weigh in.
HumanitiesModule 8
The Curators' Verdict
Five civilizations. One question your whole year has been building toward: which of them shaped the world you actually live in the most? The wheel, the alphabet, the law-code, the number system, democracy, paper — every one of them came from a people you've now investigated. This month you make the call — and you'll have to prove it, because a real audience gets to push back.
The Week-4 Challenge
As lead curator, design and present a 'Roots of the Modern World' exhibit or argument that names which civilization most shaped your world today, marshals evidence from multiple modules and sources, and answers a real audience's challenges live — a public defense beyond the parent, judged on the strength of the argument, not the decoration.
Math · The Data Desk
8 modules · 4 weeks each
You are a junior analyst at a newsroom-style 'Data Desk.' Every module is an assignment from a different beat — sports, climate, polling, civic life, design — where the only way to settle the argument is to do the math and show your work to a public audience. The year pivots from arithmetic to algebra by treating each new tool (ratios, negatives, expressions, equations, statistics) as something a real analyst reaches for to answer a question people are actually fighting about. Daily skill practice is aligned to Khan Academy Grade 6 math — each four-week module wraps the current unit in the year’s mission.
MathModule 1
Better Buy, Better Team: The Ratio Beat
Two players, two stat lines, and a city arguing about who to trade. One scores more total points; the other scores more per minute on the floor. You can't settle it by eyeballing — you need rates and percents. By Friday of week 4 you'll publish the call your readers can't argue with.
The Week-4 Challenge
Publish a 'Better Buy' verdict for a real decision (which phone plan, snack, or player is the better value). Build the ratio tables and unit rates, convert to percent, and defend the call with a chart for a public reader — co-op feed, family group, or class site.
MathModule 2
Down to the Decimal: Splitting, Scaling, and Exactness That Decides
A relief kitchen feeds 4 in a test batch but the shelter needs 300. A bulk supply ships 2.5 kilograms a bag. A field is cut into eighths and three teams each need a half — does it work? Real decisions turn on exact arithmetic: dividing fractions, dividing big numbers, and decimals down to the last digit. Get it exact or the plan falls apart in public.
The Week-4 Challenge
Run a real scale-up to spec: take a recipe, a supply list, or a relief plan and resize it for a true target (feed 300, cover a field, hit a fixed quantity). Show the fraction and decimal arithmetic exactly, then present the plan and a per-unit figure to a reader who'll check every digit.
MathModule 3
Past Zero: Mapping What Lives in the Negative
Death Valley sits 282 feet below sea level; the summit above it tops 11,000. A reservoir's level drops below its mark. A January night in Minnesota hits 14 below. The world runs on numbers smaller than zero — and once you can place them on a line and a four-quadrant grid, you can measure the distance between any two points on Earth or any two days of a record.
The Week-4 Challenge
Build a labeled 'profile of a real place or system' — an elevation cross-section of a mountain trail, a temperature year, or a month of a real budget — plotted across all four quadrants. Use ordering and absolute value to answer distance questions, and present it to an audience as a readable map.
MathModule 4
The Common Ground: Factors, Multiples, and the Fair Split
You have 24 granola bars and 36 juice boxes and you want identical snack bags with nothing left over. Two buses leave on different cycles — when do they next leave together? The answer to 'biggest equal group' and 'next time they line up' lives in factors and multiples, the hidden gears under every clean split and schedule.
The Week-4 Challenge
Solve a real 'fair split or shared schedule' problem for a group (equal kits from mixed supplies, a rotation that syncs two cycles, or a tiling that comes out even). Show the GCF/LCM reasoning and a distributive-property check, and pitch the solution to the people who'd use it.
MathModule 5
The Formula Machine: Letters That Stand for Anything
A streaming service charges a flat fee plus a price per month. A game's score is 'lives times 100 plus coins.' Instead of redoing the math for every case, real analysts write one expression with a letter in it — then it works for everyone. Exponents and a single agreed order of operations keep the whole crew getting the same answer.
The Week-4 Challenge
Design a 'pricing or scoring engine' as a reusable formula: write the expression for a real plan (a fundraiser, a game, a phone bill), evaluate it for several cases, and prove two versions are equivalent. Publish a one-page 'how the formula works' explainer for users.
MathModule 6
Pin It Down: Equations, Limits, and What-Ifs
You have $50 and tickets are $8 — how many can you buy, and what's left? A rule says you must be 'at least 13' to enter. A road trip's distance depends on the hours you drive. Each is a real question with an unknown in it — and an equation or inequality is the move that pins the unknown down or maps the whole range of what's allowed.
The Week-4 Challenge
Model a real constraint problem as equations and inequalities (a budget with a limit, an eligibility rule, a plan that scales with time). Solve it, graph the dependent-on-independent relationship, and present the answer plus the 'allowed range' to a decision-maker audience.
MathModule 7
By Design: The Geometry of Real Space
A skate ramp, a garden bed, a phone box, an aquarium for a client — every real thing that gets built starts as area, volume, and surface area on paper. Decompose a weird shape into triangles you can measure; fill a tank to a fractional depth; unfold a box into a flat net to find exactly how much cardboard it takes. Design it right on the grid and it gets built.
The Week-4 Challenge
Design and spec a real object for a client need (a planter, a container, a small structure, an aquarium): decompose shapes for area, compute volume and surface area from a net, plot the footprint on the coordinate plane, and deliver a build-ready plan with a materials estimate to the 'client.'
MathModule 8
The Whole Story: Reading a Distribution
Two classes have the same average test score — but in one, everyone's near it, and in the other, scores are all over the map. The average alone lies. Real analysts ask a statistical question, then describe the whole shape of the data: where it centers, how much it spreads, and what the picture (dot plot, histogram, box plot) is really saying before anyone draws a conclusion.
The Week-4 Challenge
Investigate a real question by collecting or finding a genuine data set (reaction times, screen-time, local weather, a survey you run). Summarize it with center, spread, and the right plot, then publish a data story that makes an honest claim — and flags what the average alone would hide — for a public audience.
Grade 7 · Ages 12-13
The year ideas collide
Find the physics hiding inside every game in Game Physics, trace how our world was argued into existence in The Age of Ideas & Revolutions, and plan a real expedition with True North.
STEM · Game Physics
8 modules · 4 weeks each
Every module enters the physics of forces, fields, energy, waves, the body, and the Earth through something a 13-year-old already loves and argues about — sports, video games, music, theme parks, esports reflexes, extreme places. Play is engineering in disguise: a half-pipe, a controller, a guitar, a roller coaster, and a fault line are all the same physics dressed for fun — and the year ends by engineering play that's better, fairer, or safer for a real audience.
STEMModule 1
Stick the Landing
A skater drops a 12-foot vert ramp, a gymnast lands a vault, a running back gets hit and gets up — and every one of them is doing math with their body, whether they know it or not. The argument's already in your group chat: is it harder to start moving or to stop? Settle it with real measurements, then engineer the landing that lets you fall farther without getting hurt.
The Week-4 Challenge
As junior sports engineers, design and test a landing or impact system — a padded drop rig, a model 'safe-fall' surface, or a tested technique with before/after force data — and present a coach's-clinic explainer (video or demo) to teammates, family, or an online audience arguing the physics behind the safe move.
STEMModule 2
No Wires
Your controller rumbles, your phone charges lying on a pad, and a Japanese train floats on magnets at 300 mph — none of them touching what moves them. There's a force reaching across the gap, and game designers, phone makers, and train engineers all bend it on purpose. Build the motor or magnet that makes it happen and measure what makes the reach stronger.
The Week-4 Challenge
As junior device engineers, build a working electromagnet or motor (the guts of a rumble pack or a maglev demo), run a controlled investigation proving the field exists and what strengthens it, and demo your 'no-wires' device with its data to family or a co-op tech share.
STEMModule 3
Top of the Loop
At the very top of a roller-coaster loop you're upside down, weightless, and not buckled in tightly enough to explain why you don't fall — and the coaster has no engine past the first hill. All that ride is energy, trading height for speed and back, with heat quietly stealing some at every turn. Design the hill that delivers the biggest thrill your track can survive.
The Week-4 Challenge
As junior ride engineers, design, build, and test a marble or ball coaster (or a stored-energy launcher) that completes a loop or hits a target, log the energy story with measurements, and present your ride with its data to a family showcase or an online maker audience — arguing how you spent every joule.
STEMModule 4
Drop the Bass
A bass note you can feel in your chest and a game's footstep-radar that tells you exactly where the enemy is are the same thing: a wave carrying information through the air. Turn that wave into a code and it survives noise, compression, and a bad connection. Build the instrument or the signal that gets the message through clean.
The Week-4 Challenge
As junior audio/signal engineers, build and tune a real wave system — an instrument tuned to pitch, a soundproofing test, or a digital-vs-analog 'survive the static' showdown — and perform or demo it with the data to a real audience, arguing why digital encoding wins.
STEMModule 5
Frame Rate
Pro gamers and pro athletes win on the same edge: the few hundredths of a second between a thing happening and their body answering. Your reflex fires before you 'decide,' your eyes only see a fraction of what's there, and your trained reactions beat your thinking ones. Measure your own frame rate, then prove how a body can be trained — or fooled.
The Week-4 Challenge
As junior performance scientists, design and run a fair reaction-time or perception investigation on a real sample of testers (training effect, distraction, sense vs. sense), analyze the data, and deliver findings — a video, infographic, or talk — arguing how a coach or game designer should use the body's limits, to a peer or online audience.
STEMModule 6
Hard Mode: Earth
Game designers building a believable open world have to fake what Earth does for real — mountains rising, oceans opening, the ground rupturing along lines that aren't random. Those lines are plate boundaries, and the same coastlines and fossils split across two continents prove the map used to be one piece. Read the planet's real level-design and you can predict where it 'spawns' an earthquake.
The Week-4 Challenge
As junior world-builders and geologists, reconstruct plate motion from real evidence into a case (evidence map or 'how we know' argument) and build a shake-table to test two structures, then present both the evidence case and the build — pitched as level-design realism or a real hazard map — to a co-op or family audience.
STEMModule 7
Weather the Game
Storm chasers, surfers, and the people who decide whether the big game gets called all read the same machine: the Sun heating the planet unevenly while it spins, driving every wind and current on Earth. A real warming dataset shows the machine shifting. Model the engine and you can explain a forecast — and argue one against someone who's wrong.
The Week-4 Challenge
As junior climate scientists, build a working model of one circulation driver (convection, Coriolis, ocean current, albedo), analyze a real climate dataset, and produce an evidence-based briefing — documentary, data story, or panel — for a public/online audience that explains a regional pattern and weighs one proposed response.
STEMModule 8
Boss Level: Build the Game
Every game, ride, sport, and gadget you love is a settled argument: somebody chose between options that were each good in different ways, and tested until one won. Now it's your turn to make the call. Take a year of forces, energy, waves, and the body and engineer your own thing — a game mechanic, a ride, a piece of gear — then defend why your design beats the alternative to a panel that gets to judge.
The Week-4 Challenge
As lead designers, run a full competing-solutions showdown on a play-or-product problem of your choice (a game mechanic, ride, instrument, or piece of gear from any module): generate two-plus designs, build and test them against a shared criteria/constraints rubric, and defend your selection with test data to a panel of peers, family, or an online audience.
Humanities · The Age of Ideas & Revolutions
8 modules · 4 weeks each
A forward march from the fall of Rome's eastern half to the smokestacks of industrial America, told one era at a time. In every module you read the people who were actually there — a Byzantine empress's secret memoir, a Baghdad scholar's notebook, a Florentine artist's contract, a philosopher's pamphlet, a revolutionary's declaration, a mill girl's letter, a constitutional debate — and then you take a position and defend it with their own words. History stops being a list of dates and becomes a sequence of arguments people won or lost, each one changing what came next.
HumanitiesModule 1
The Empire That Wouldn't Die
Rome fell in 476 — except the half of it nobody tells you about kept going for another thousand years, ruling from a city wrapped in the largest walls on Earth and ruled, at its peak, beside an empress who had been an actress and a circus performer. A courtier named Procopius wrote the official glowing history of her reign by day and a secret tell-all by night, calling those same rulers monsters. You get both books. Which Procopius do you believe — and how would you ever know?
The Week-4 Challenge
As a documentary writer-narrator for a 'History's Disputed Figures' channel aimed at other teens, script and record (or storyboard) a 4-minute portrait of Empress Theodora or Emperor Justinian that openly weighs Procopius's two contradictory accounts against modern historians, then takes and defends your own verdict on the person. Deliver it to an audience beyond your grown-up — a co-op, a family screening, or an online post. Callback to the hook: you got both Procopius books — now you tell the room which one earned your trust, and why.
HumanitiesModule 2
The House of Wisdom
Around the year 800, while much of Europe had stopped copying old books, the rulers of Baghdad were paying scholars the weight of a translated manuscript in gold. In one library — the House of Wisdom — thinkers preserved Greek science the West had lost, invented algebra, mapped the stars, and ran the first hospitals with case notes. The word 'algorithm' is a man's name. A thousand years of ideas you use every day were saved and grown here. Why did this become the most learned city on Earth — and why don't most timelines mention it?
The Week-4 Challenge
As a researcher-curator building an exhibit for a 'Hidden Histories' museum gallery (real audience: a co-op showcase or shared online gallery), produce a 5-panel exhibit on a Golden-Age contribution you research — algebra, optics, hospital medicine, star maps, paper-making, or a translated text — each panel making one claim, backed by quoted-and-cited evidence from at least two sources you judged credible. Open the gallery with a wall card answering the essential question. Callback: you found out why the timelines skip this — now put it back on the wall where people will see it.
HumanitiesModule 3
Reborn — and Split in Two
In one lifetime, a Florentine teenager could watch artists figure out how to paint a flat wall so convincingly you'd try to walk into it, while a monk in Germany nailed a list of complaints to a church door and accidentally broke European Christianity in half — using a brand-new machine, the printing press, to spread his words faster than any king could stop them. Two revolutions, one century, one engine. What happens to a world when, for the first time, an idea can outrun the people trying to suppress it?
The Week-4 Challenge
As an editorial writer for a teen-run 'history desk,' choose a genuinely contested Renaissance-or-Reformation figure or event (Luther, the Medici, the printing press itself, an indulgence, Galileo's early clash) and write a 600-800-word evidence essay that puts two real sources or historians side by side, shows where they emphasize different evidence, and argues which is more persuasive. Publish it for a public reader — a co-op blog, a printed 'gazette,' or a read-aloud panel. Callback: an idea outran its censors once — now you weigh the two versions history left us.
HumanitiesModule 4
Dare to Know
For most of history, the answer to 'why is the world this way?' was 'because that's how it has always been.' Then a handful of people — looking through new telescopes, writing dangerous pamphlets in cafés — started insisting you could reason your way to a better answer, even about kings, even about God. Some were jailed. Some changed nations. One short essay's motto was just two words: 'Dare to know.' You're going to read these arguments the way their first readers did — and judge whether they actually hold up.
The Week-4 Challenge
As an op-ed writer for a publication that runs 'arguments that changed the world,' pick one Enlightenment thinker's real claim (natural rights, separation of powers, the social contract, the rights of women) and write a 700-900-word argument essay that traces the original author's reasoning, names its strongest and weakest evidence, raises a genuine counterclaim, and then states and defends your own position on whether the idea holds up today. Present it to a live audience for questions. Callback: 'Dare to know' was their dare — now you dare to judge whether they were right.
HumanitiesModule 5
When the People Said Enough
In 1789, the cost of bread in Paris was eating up most of a worker's wages while the queen reportedly shrugged 'let them eat cake.' Within months a mob took a fortress prison, a king lost his crown — and then his head — and a document declaring that all men are born free rewrote what a government was for. Within a generation the idea jumped oceans and toppled empires. What turns a hungry, angry crowd into a revolution that actually changes the world — and was the violence worth it?
The Week-4 Challenge
As a historian-storyteller for a 'Causes & Consequences' series, build a piece that does two things: maps the multiple causes of a revolution (French, Haitian, or a Latin American independence movement) using real sources, and then argues a position on whether the revolution's results justified its violence — acknowledging the strongest objection to your view. Share it with an audience beyond the family. Callback: a hungry crowd became a revolution — now you weigh whether the world it built was worth the blood it cost.
HumanitiesModule 6
Smoke, Steam, and the Twelve-Hour Day
For thousands of years, almost everything humans owned was made by hand, slowly, near home. Then steam engines, blast furnaces, and power looms arrived — and within a century, kids your age were working twelve-hour shifts in cotton mills, cities tripled in size, and a worker could buy cloth that once cost a month's pay. The Industrial Revolution gave us almost everything in your room and a list of horrors to go with it. Was the trade worth it — and who got to decide?
The Week-4 Challenge
As an investigative journalist for an 1840s-style exposé OR a modern retrospective, research the Industrial Revolution using at least three primary sources (a worker's testimony, an owner's or economist's defense, a reformer's report) and write a 700-900-word explanatory feature that lays out who gained, who paid, and how the system actually worked — letting the sources speak and citing each. Publish to a real reader. Callback: everything in your room came from this trade — now show your readers the receipt, with the costs printed in.
HumanitiesModule 7
Arguing a Country Into Existence
In the summer of 1787, fifty-five men locked themselves in a hot Philadelphia room, nailed the windows shut so no one could leak the fight, and spent four months arguing about how to build a government from scratch — because the first version they'd tried was already falling apart. They disagreed about almost everything: big states versus small, who counts as a person, how much power one leader should hold. The country you'd recognize came out of that argument. You're going to step into the room and take a side.
The Week-4 Challenge
As a delegate-turned-columnist, take one real Constitutional Convention fight (representation, executive power, the Bill of Rights, the unresolved question of slavery) and write a 700-900-word argument that states your position, builds it on evidence from the actual debates or the Federalist/Anti-Federalist papers, fairly represents the strongest opposing claim, and answers it. Defend it in a live ratification-style debate. Callback: the windows were nailed shut so the argument could be honest — now make yours in the open and win the room.
HumanitiesModule 8
The Unfinished Country
America promised, on paper, that all men are created equal — and then spent its first century deciding the promise didn't apply to enslaved people, to women, to workers, to the people already living on the land. So a different kind of fight started: not armies, but words. Abolitionists, suffragists, labor organizers, and writers used speeches, newspapers, and protests to force the country to keep its own promise. Some of those fights are still going. Which unfinished promise will you take up — and how do you actually move people with an argument?
The Week-4 Challenge
As an advocate writing in the tradition of America's reformers, research one reform movement (abolition, suffrage, labor, or its modern continuation) using at least two primary sources and two historians, then deliver a persuasive product — speech, op-ed, or campaign — that argues for action on an unfinished version of that issue, names and answers the strongest objection, and proposes a real, do-able step. Present it to a public audience. Callback: the country's promise is still unfinished — now you pick up the pen the reformers handed down and aim it at a fight that's still open.

The whole year hands a 13-year-old the job adults usually keep for themselves: planning a real expedition — the route, the rations, the gear, the forecast, the call. Proportional reasoning becomes calories per ounce; percent becomes the pack-weight rule; signed numbers become elevation lost and temperatures below zero; equations become the supply formula that says how far you can go; scale and geometry become the topographic map; probability becomes the weather odds behind a go/no-go call. Every module ends with the student defending a plan from the numbers — because in the backcountry the math isn't a worksheet, it's the margin between a good story and a bad one. Daily skill practice is aligned to Khan Academy Grade 7 math — each four-week module wraps the current unit in the year’s mission.
MathModule 1
Calories per Ounce
Thru-hikers rank every food in their pack by one number — calories per ounce — because hauling a heavy snack that doesn't feed you is how a trip falls apart. Your pace is a rate too: time yourself on one known mile and you can predict your arrival at a campsite ten miles out. Get the unit rates right and a wild place stops being a guess; get them wrong and you're hungry, thirsty, and hiking in the dark.
The Week-4 Challenge
As a junior expedition planner, build the rations-and-pace plan for a real outing your family or co-op could actually take: compute calories per ounce for real foods, liters per person per day, and your own measured pace from a timed test mile, then publish a one-page trip plan — tables, a pace graph, and totals — for the people who would carry it. Defend why the unit rates, not guesses, set the plan.
MathModule 2
The Twenty Percent Rule
A loaded pack should weigh no more than about 20% of the person carrying it — which means the right pack weight is different for you than for your dad, and somebody in your crew is probably over the line right now. Outfitting that crew is a chain of percents: the 30%-off sale, the 8% tax, the upgrade that cuts a tent's weight by 15%, the trail that climbs at a 10% grade. Untangle the chain and you can gear up a whole expedition on a real budget without breaking anyone's back.
The Week-4 Challenge
As a junior outfitter, gear up a real or realistic crew under two hard caps — a budget and the pack-weight percent rule: price real gear through its chain of percents (sale, tax, weight-saving upgrades), check every crew member's load against the rule, and present the cost-and-load sheet to the crew (family or co-op outing group), with every chained percent shown.
MathModule 3
The Elevation Profile
A trailhead sign says the summit is 1,100 feet above you — but the elevation profile shows your legs will climb more than 3,000, because the trail keeps dropping into ravines and giving your hard-won feet back. Every dip is a negative number, every climb a positive one, and only signed addition tells you what the day will really cost. Read a profile like that and no 'easy' trail will ever ambush you again.
The Week-4 Challenge
As a junior route analyst, take a real trail's elevation profile and turn it into a signed-number story: model every climb and descent as a signed move, compute net change versus total ascent ('what the sign says' vs. 'what your legs pay'), and present a 'true cost of this trail' breakdown — number line, running totals, biggest swing — to a hiking audience deciding whether to take it on.
MathModule 4
The Lapse Rate
It's 72° in the parking lot, and the air above you is running an equation: roughly -3.5° for every 1,000 feet you climb. Multiply that negative rate by a 4,000-foot ascent and the summit is doing 58° before any wind — keep going up a big peak and the answer crosses below zero while you're still sweating. Multiplying and dividing with negatives is how mountaineers, pilots, and forecasters predict cold they can't see yet.
The Week-4 Challenge
As a junior mountain forecaster, predict the summit: take real base temperatures and the lapse rate, use signed multiplication to forecast conditions at altitude on several real peaks — including where the answer crosses below zero — then check your forecasts against real summit-station data and present a 'what to wear up there' card with the signed math shown.
MathModule 5
The Resupply Equation
On day one your pack is a formula: a fixed base weight plus about a pound and a half of food per person per day, times the days until you can restock. Write it as an equation and the scariest question on the route — 'how many days can we actually go?' — becomes solve-for-x. The crews that come home on schedule are the ones who did the algebra before they laced up.
The Week-4 Challenge
As a junior logistics chief, write the supply plan for a multi-day route as algebra: build the pack-weight expression (base plus daily rate times days), solve equations and inequalities for the longest leg your supplies allow and the break-even between two resupply strategies, and present the plan — formula, solution, verdict — to the crew that would hike it.
MathModule 6
Take a Bearing
A topographic map whispers '1:24,000' in the corner, and that one ratio turns two finger-widths of paper into a real mile of canyon. Lost without GPS? Take a compass bearing on two peaks you can name, draw the two lines, and the triangle rules guarantee they cross at exactly one point — you. Scale and angles are the oldest navigation tech there is, and they still work when every battery is dead.
The Week-4 Challenge
As a junior navigator, plan a route on a real USGS topographic map: convert map measurements to true distances and areas with the scale, plot compass bearings, and run a triangulation fix (in the field or on a backyard orienteering course) to prove you can locate a point with two angles. Present the route card and the fix to your crew, defending the scale math and the geometry.
MathModule 7
The Contour Line
Every contour line on a map is a slice — cut the mountain flat every 40 feet of height and stack the outlines, and you've drawn a 3-D landform on a 2-D page. The same measurement math settles the un-skippable gear questions: will six days of food actually fit inside one bear canister, and how much fabric does it take to keep a tent dry? Circles, surface area, and volume are how you pack for a mountain — and how you read the mountain itself.
The Week-4 Challenge
As a junior gear-and-terrain analyst, choose your case: model a real landform by cutting and stacking its contour cross-sections, or settle a real packing question — does the food fit the bear canister, how much fabric keeps the tent dry, which container hauls more per ounce — with circle, surface-area, and volume math. Publish a measured, sketched report for an outdoor-crew audience, math shown.
MathModule 8
Go or No-Go
The forecast says '30% chance of storms' for your summit day — but 30% of what, exactly, and is it enough to call off six months of planning? Real expedition leaders make the go/no-go call from samples: dozens of past trip reports, years of weather records for that one ridge, the odds of two clear days in a row. Learn sampling and probability and the biggest decision of a trip stops being a vibe and becomes a number you can defend.
The Week-4 Challenge
As a junior expedition safety officer, make the go/no-go call for a real planned outing: sample past weather records and trip reports for the route and date, build a probability model (with a simulation for compound events like two clear days in a row), compare alternative routes from the data, and present a recommendation — with the sampling math, the odds, and the uncertainty stated honestly — to the people who would actually go.
Grade 8 · Ages 13-14
The year they work like experts
Read the planet’s evidence like a forensic scientist in Evidence & Change, follow The Making of the Modern World, and design at full size in Built to Scale.
STEM · Evidence & Change
8 modules · 4 weeks each
Every module hands the student a real piece of evidence — a residue, a bone, an inherited trait, a layer of rock, a temperature record — and asks them to reason like an investigator: what changed here, what stayed the same, and how do we know? That one question runs as a year-long detective frame from the atom to the planet, ending in an engineering capstone that fixes something the evidence revealed.
STEMModule 1
Trace Evidence
A lab gets a sealed bag: a stain on a shirt, a white powder, a length of melted wire. Nothing in the bag is labeled — and your job is to prove, with data only, whether a chemical reaction happened here or whether someone is bluffing. You'll measure mass before and after, watch for the five signs of a real reaction, and learn the law a forger can't beat: atoms are never created or destroyed, so the books always have to balance.
The Week-4 Challenge
As a forensic chemistry team, students take a set of unknown 'case samples' (household reactions and physical changes staged as evidence), run before/after property tests, build a balanced particle model showing mass is conserved, and present a signed lab report to a panel of family or co-op 'jurors' who must reach a verdict on what really happened.
STEMModule 2
Built From What You Eat
Right now, the atoms in your breakfast are being taken apart and rebuilt into you — into muscle, bone, and the energy reading this sentence. A bodybuilder and a marathoner eat to win opposite battles with the same chemistry. So here's the case: two athletes, two diets, two bodies. You'll trace where the atoms go and prove that 'you are what you eat' is a chemical equation, not a slogan.
The Week-4 Challenge
As performance nutritionists, students model how a real athlete's food is rearranged through chemical reactions to build tissue and release energy, design an evidence-based fueling plan for a chosen sport or goal, and pitch it (with the molecular reasoning shown) to a 'client' — a family member, coach, or online fitness audience.
STEMModule 3
Inheritance Case File
Someone was poisoned at the old DuBois estate, and the only clues left behind are traits — eye color, a widow's peak, a rare blood type, a genetic condition no one talks about. Five relatives could have done it. You'll use Punnett squares and a single drop of inherited evidence to clear the innocent and corner the one person whose genes give them away. One mutation changes everything.
The Week-4 Challenge
As genetic investigators, students solve a multi-suspect 'inheritance mystery' using Punnett-square models and trait evidence, then write and present a case report — including a clear stance on a real DNA-privacy dilemma (genetic testing, ancestry databases, or genetic discrimination) — to a co-op panel or online forum.
STEMModule 4
Reading the Bones
A whale has finger bones inside its flipper. A snake has the tiny stumps of legs it never uses. A python and a person share the same arm blueprint. These aren't coincidences — they're a confession. Bones and fossils are a record that can't be edited after the fact, and once you learn to read them, you can reconstruct a story of life that's millions of years long from the evidence in a single skeleton.
The Week-4 Challenge
As paleontologists, students analyze real fossil-record and anatomy datasets to build a cladogram and a reconstructed evolutionary story for a chosen lineage (whales, horses, birds-from-dinosaurs), then mount a 'museum exhibit' — physical or digital — that walks visitors through the evidence for a public audience.
STEMModule 5
Survival of the Fittest, by the Numbers
On one island, a drought hits, and within a single year the average finch beak gets measurably bigger — scientists watched it happen and have the data to prove it. Bacteria in a hospital can do the same trick in days, which is why a once-unbeatable antibiotic now fails. Natural selection isn't a slow story from a textbook; it's a math problem running in real time, and you can predict the next move.
The Week-4 Challenge
As population biologists, students run a selection simulation (predator-prey, drought, or antibiotic pressure), use mathematical representations to model how a trait's frequency changes over generations, and present a data-backed briefing on a real evolution-in-action problem (antibiotic resistance, resistant pests, or a conservation case) to a panel or online audience.
STEMModule 6
The Planet's Diary
Earth keeps a diary, and it never lies. Every layer of rock is a dated page, every fossil a pressed flower, every ash band a catastrophe with a timestamp. Stacked up, those pages reach back 4.6 billion years — and they record five times life nearly ended. You'll learn to read the strata, place the great extinctions on a scaled timeline, and find out which page we're writing right now.
The Week-4 Challenge
As geologists, students build a scaled geologic timeline (a hallway, a wall, a digital scroll) from real strata and fossil evidence, mark the major events and mass extinctions, and stage a public 'walk through deep time' for family, neighbors, or an online audience that ends by placing the present moment on the same scale.
STEMModule 7
The Fingerprints We Leave
Eight billion people, all needing water, food, metal, and power — and the planet's systems are showing the strain in numbers you can actually graph. The thermometer has climbed for a century, and the question everyone argues about online has a real, checkable answer hiding in the data. You'll stop taking sides on vibes. You'll get the actual datasets, find the human fingerprint, and decide what the evidence does and doesn't prove.
The Week-4 Challenge
As climate data analysts, students interrogate real population, resource-use, and temperature datasets to construct an evidence-based argument about a specific human impact, then deliver it as a public briefing — to a community group, a mock town council, or an online audience — that separates what the data proves from what it doesn't and proposes a defensible response.
STEMModule 8
Heat on Demand
A hiker is going hypothermic and there's no fire — but a sealed pouch with two chemicals inside can save them by getting warm on command. An athlete's swelling needs the opposite: instant cold, no ice. Both are chemistry you can engineer. This is the capstone: you'll design two competing heat (or cold) devices, test them on real data, and prove your final version is better than either one alone.
The Week-4 Challenge
As engineers, students run the full design cycle to build a chemical hand-warmer or cold-pack for a real user need: they define criteria and constraints, build and test two competing designs, analyze the temperature data to find the best feature of each, and combine them into an optimized final device — pitched, with its test data, to a panel acting as the client.
Humanities · The Making of the Modern World
8 modules · 4 weeks each
A chronological door through the modern era, 1870 to now: each module is the next link in one causal chain — empire built the rivalries that lit World War I, the unfinished peace and the Depression bred the dictators and the Holocaust, the bomb ended one war and opened the Cold War, the Cold War's edges became decolonization, and America's own Gilded-Age-to-civil-rights arc ran alongside it all — closing with an informed-action capstone where students stop reading history and make a piece of it.
HumanitiesModule 1
The Scramble: Drawing the Lines
In the winter of 1884, fourteen men met in a Berlin sitting room with a single map of Africa on the wall — a continent none of them had walked across — and over a few months drew the borders that still run through it today, splitting families and fusing enemies with a pencil. No African was in the room. This month you read the actual treaties and travel accounts the lines were built on, and decide for yourself: when a powerful country says it is 'bringing civilization,' whose story is being told, and whose is being erased?
The Week-4 Challenge
As a documentary research team, students build a two-voice 'contested history' exhibit on one real colonized place (e.g., the Congo, India, the Philippines): a primary-source panel from the colonizer's argument set beside a panel from a colonized writer or testimony, with a written analysis of where the two accounts disagree on fact versus interpretation. The exhibit is presented to a co-op or family panel who must judge which claims each side actually supports.
HumanitiesModule 2
Gilded: The Age of Robber Barons
By 1890 a single American family controlled more wealth than the bottom half of the whole country, children worked fourteen-hour days in the mills, and immigrants poured through Ellis Island into tenements where families of nine shared one room. They called it the Gilded Age — gilded, meaning gold paint over something cheaper. This month you read the muckrakers, the labor songs, and the photographs of Jacob Riis, and you investigate what that gold paint was hiding.
The Week-4 Challenge
As a muckraking journalist for the era's press, the student writes an investigative feature exposing one real Gilded-Age injustice (child labor, tenement conditions, a specific strike, monopoly power), drawing on primary photographs, testimony, and statistics, and ending with a call to action — modeled on the real exposés that drove reform. Published to a class 'newspaper' or read aloud at a community showcase.
HumanitiesModule 3
How a Whole World Caught Fire
On one June morning in 1914, a single revolver in a Sarajevo street killed an archduke most people had never heard of — and within six weeks, men from four continents were marching toward trenches that would swallow a generation. How does one murder become twenty million deaths? This month you trace the alliances, the propaganda posters, and the front-page lies, and you build the case for what truly pulled the world over the edge.
The Week-4 Challenge
As a historian, the student writes and presents an evidence-based argument essay answering 'What caused the First World War?' — staking a clear claim, weighing at least one opposing explanation, and citing primary sources (a treaty, a recruitment poster, a soldier's letter). The argument is delivered to a public audience as a written op-ed plus a short spoken defense where listeners get to push back.
HumanitiesModule 4
When People Choose the Strongman
In 1933 a country that had just held free elections handed nearly absolute power to a man who promised to make it great again — legally, by a vote, with crowds cheering. Within a few years neighbors were informing on neighbors and a continent was at war. How does a democracy talk itself into a dictatorship? This month you read the real speeches, diaries, and laws, and you study how ordinary people became bystanders — so you can recognize the warning signs anywhere.
The Week-4 Challenge
As a memorial curator, the student creates a 'first they came…' reflective narrative-and-source piece centered on one real act of resistance or one real bystander choice from the era (e.g., the White Rose, a rescuer, a town that complied), pairing a researched account with the student's own narrative reconstruction of the decision-point. Shared at a public 'never again' showcase for family or community, framed as a warning to the present.
HumanitiesModule 5
The Decision: Hiroshima
In August 1945 one bomb erased a city in nine seconds, and the man who ordered it believed he was saving lives by ending a war. Seventy-some years later, people still cannot agree whether he was a hero or a war criminal — and the documents that would settle it contradict each other. This month you read the survivors' accounts, the generals' memos, and the casualty estimates, and you take a side you can defend.
The Week-4 Challenge
As a member of a citizens' tribunal, the student writes and argues a position brief on the question 'Was dropping the atomic bomb justified?' — required to represent the strongest version of the opposing view before answering it, and to cite a survivor account, a military document, and a casualty estimate. Briefs are argued before a deliberating panel (family or co-op) that votes after hearing both sides.
HumanitiesModule 6
The Iron Curtain and the Fight to Be Free
For forty years two superpowers that never directly fought each other still divided the planet down the middle — building a wall through the heart of a city, racing to the moon, and pointing enough missiles at each other to end the world. Meanwhile, across Africa and Asia, dozens of nations were tearing down old empires and inventing themselves overnight. This month you read the speeches, the spy cases, and the independence declarations, and you map how the whole world rearranged itself.
The Week-4 Challenge
As an investigative researcher, the student conducts a short research project on one real decolonization or Cold War flashpoint (e.g., Indian independence, Ghana, the Berlin Wall, the Cuban Missile Crisis), assessing sources from both sides and producing a researched explainer that distinguishes fact from framing. Published for an online or community audience as a sourced, citation-backed brief.
HumanitiesModule 7
The Long Fight for Rights
In 1963 a teenager not much older than you walked out of a Birmingham church and into police dogs and fire hoses — on purpose, on camera, because the pictures would do what words alone couldn't. The modern civil rights movement was won in courtrooms and on streets, but also in living rooms, by people who understood that a photograph or a televised march could change a nation's mind. This month you read the letters, speeches, and laws, and you study how ordinary citizens forced change — and how they argued for it.
The Week-4 Challenge
As a rhetoric analyst and advocate, the student close-reads one landmark text of a rights movement (e.g., 'Letter from Birmingham Jail,' a suffrage speech, a Cesar Chavez address), writes an analysis of how its argument and language work, then composes an original persuasive speech applying those techniques to a cause they choose. Delivered live to a peer or community audience.
HumanitiesModule 8
Your Turn: Make a Piece of History
For seven months you've studied people who refused to be bystanders — who took one real problem and did something about it, with evidence and an argument instead of just an opinion. Now it's your move. This month you pick a real issue in your own community or country, build the strongest case you can from sources, and take a genuine civic action — to an actual decision-maker, public body, or audience — the way every reformer you've studied once did.
The Week-4 Challenge
As an active citizen, the student runs a full C3 informed-action capstone: choose a real local, regional, or global issue; research and weigh multiple sources; write an argument that names its strongest counterclaim; assess the levers of power and possible strategies; and take a genuine civic action delivered to a real audience or decision-maker (a letter to an official, public testimony, a community campaign, an organized event). Reflection assesses what changed and what they'd do next.
Math · Built to Scale
8 modules · 4 weeks each
Every module hands the student a real design commission and the math is the tool that makes it buildable. The student plays an architect, engineer, game designer, or studio lead who has to make something WORK at scale — a structure, a price model, a forecast, a level, a logo system, a stadium. Each Khan unit becomes a maker's instrument: irrational numbers and roots size diagonals and braces, scientific notation specs materials from microns to megastructures, linear functions model cost and growth, transformations lay out symmetric designs and prove a brand is consistent, and the Pythagorean theorem squares up every build. The year ends with a full design pitch backed by data — the grade-8 shift from solving problems to engineering solutions for a client. Daily skill practice is aligned to Khan Academy Grade 8 math — each four-week module wraps the current unit in the year’s mission.
MathModule 1
The Diagonal Problem
You're designing a square skate ramp, and you need to cut the diagonal brace that runs corner to corner. Your tape says it's about 1.41 meters per meter of side — but the digits never stop and never settle. That brace length is the square root of 2, a number that can't be written as any fraction, and every builder in history has had to wrestle it. This month you'll learn which lengths are 'clean' fractions and which run forever like √2, and how to cut an endless number down to a measurement precise enough to actually build.
The Week-4 Challenge
As a fabrication designer, the student specs the precise diagonal, brace, or hypotenuse measurements for a real small build (a ramp, a frame, a shelf, a planter), classifies each needed length as rational or irrational, converts any repeating-decimal dimensions to exact fractions, brackets each irrational length between tight rational bounds with a stated tolerance, and delivers a buildable cut list to a 'shop' audience (family, maker space, co-op).
MathModule 2
From Microns to Megastructures
You're spec'ing a bridge that has to carry 200,000 cars a day, bolted with parts machined to 0.0001 of a meter, near a river that moves 3,000,000 liters a minute. Written out, those numbers are unworkable on a drawing — and a single misplaced zero collapses the design. Scientific notation is how every engineer specs the very large and very small on the same sheet. This month you'll use exponent laws and scientific notation to size everything from a microchip's transistor to a skyscraper's load, and catch the order-of-magnitude error that ends careers.
The Week-4 Challenge
As a design engineer, the student writes the full spec for a real-scale system that spans tiny-to-huge magnitudes (a building, a vehicle, a device), expresses every quantity in scientific notation, uses exponent laws to compute ratios, totals, and per-unit values, runs an order-of-magnitude check that flags any impossible figure, and presents the spec sheet to a 'review board' of family, mentors, or an online maker audience.
MathModule 3
Find the Break-Even
You're launching a product and pricing it. Make it yourself for $40 plus $3 a unit, or outsource for a flat $12 a unit — somewhere there's a quantity where the two costs are exactly equal, and pricing it wrong sinks the launch. This month you'll turn any 'when do these costs match?' question into one equation in one unknown and solve it cleanly — including the cases with no solution or infinitely many, where two plans never meet or are secretly identical. Find the break-even, and you know exactly when each option wins.
The Week-4 Challenge
As a product designer pricing a launch, the student models two real production-or-pricing paths (make vs. buy, two suppliers, two material choices) as linear expressions, solves for the break-even unknown, identifies any no-solution or infinitely-many case, and pitches a pricing recommendation with the break-even math shown to a 'startup board' of family, peers, or mentors.
MathModule 4
The Slope of Everything
Every ramp has a rise-over-run that decides if a wheelchair can climb it or a skateboard can bomb it; every cost model has a per-unit slope; every growth chart has a rate that tells you when to scale up. Slope is the single number that captures how steep anything is, and it's the heart of design. This month you'll read slope as a rate, prove with similar triangles why a line is equally steep everywhere, and build y = mx + b to model and forecast any steady design relationship — and to spec a ramp that actually meets code.
The Week-4 Challenge
As a design engineer, the student takes a real linear design relationship (a ramp grade, a cost-per-unit, a fill rate, a growth trend), fits a line, derives y = mx + b, interprets the slope and intercept as design facts, uses the model to hit a target or check a code requirement, and presents the spec — with its assumptions — to a review audience.
MathModule 5
The Reliable Machine
A game where pressing 'jump' sometimes ducks would be unplayable. A function is the rule that guarantees it won't — one input, one output, every single time — and it's the contract behind every system you design, from a damage formula to a pricing tier to a level's difficulty curve. This month you'll learn to spot a true function from a broken one, compare two designs given in different forms (a graph vs. a rule) to see which performs better, and tell a steady linear curve from one that ramps out of control — the difference between a balanced game and a broken one.
The Week-4 Challenge
As a systems or game designer, the student models two real design relationships given in DIFFERENT forms (one graph, one table or rule — a difficulty curve, a pricing tier, a scoring system), proves each is or isn't a function, classifies each as linear or nonlinear, compares their rate of change and starting value, and recommends the better design with the cross-form reasoning shown to a player or client audience.
MathModule 6
Two Plans, One Crossing
You're designing a venue and have to choose: a $2,000 flat rental plus $5 a guest, or a $0 base plus $20 a guest. For a small party one wins; for a big one the other does — and the crossover guest count decides everything. A system of equations is two design plans on the same graph, and where the lines cross is the exact point they tie. This month you'll find that crossing three ways — graph, substitution, elimination — and use it to make real either/or design calls: which plan, which material, which route, and when each one wins.
The Week-4 Challenge
As a project designer making a scaling decision, the student models a real two-plan tradeoff (flat-vs-per-unit pricing, two materials, two layouts) as a system of linear equations, solves it by graphing AND algebraically, interprets the crossover point as the design decision boundary (and explains any parallel/no-crossover case), and pitches the size-dependent recommendation to a client or board.
MathModule 7
Symmetry, Scale & the Brand
A great logo works flipped on a phone, blown up on a billboard, and rotated on packaging — and it has to be PROVABLY the same shape every time, or the brand looks broken. This month you'll master the moves designers use to lay out and scale a design — slides, flips, turns, and resizes — and learn to prove two versions are congruent (identical) or similar (scaled), the way a brand team guarantees consistency across every screen and surface. You'll also use the angle rules of parallel lines and triangles to build layouts that line up perfectly.
The Week-4 Challenge
As a brand or layout designer, the student creates a design system (a logo set, tiling pattern, or responsive layout), specifies the exact transformations in coordinates that scale and reposition it across surfaces, proves two versions are congruent or similar with an angle-and-side argument, and presents the design system to a client or audience as proof of consistency.
MathModule 8
The Build That Proves Itself
This is your final commission: design something real — a structure, a stadium section, a product — and prove with numbers that it works. The Pythagorean theorem squares up every corner and sizes every diagonal brace; the volume formulas tell you exactly how much concrete fills a column, how much water fills a tank, how much material molds a dome. And the capstone move: gather real data on how your design performs or sells, plot it, fit a line, and let the numbers argue your design is the right one — then pitch the whole thing to a real audience.
The Week-4 Challenge
As a lead designer, the student delivers a full data-backed design: uses the Pythagorean theorem to size and square at least one real diagonal or structural element (including a coordinate-grid distance), computes at least one cylinder/cone/sphere volume the design needs, gathers real bivariate data on a relevant tradeoff or performance question, builds a scatter plot and trend line, and pitches the design — with the slope, association, and any two-way breakdown as evidence — to a public audience or panel.
