For kids finishing 3rd, 4th, or 5th grade

Don't spend the summer wondering if your kids will be ready when school starts.

For just 11 days, let your child journey to Mathedonia - and walk into the new school year with this year's math locked in and next year's already begun.

  • No lessons - each day is a QUEST: a guided battle, a solo battle, and a boss fight
  • Complete a quest a day, and the entire grade's review is done in under two weeks
  • Fully self-paced - a page a day is a perfectly good day for a hero
  • The full grade's curriculum, reviewed the way top classrooms around the world teach it
  • Zero screens, zero prep, complete answer key - no math confidence required from you

How it works

Three steps. Eleven days. Ready.

1

Pick the grade they just finished

Book 1, 2, or 3 - each one reviews the whole year your child just completed, restructured as an adventure.

2

One quest frees one city

A guided battle, a solo battle, a boss fight, and an optional challenge page - taken at whatever pace fits your hero. A quest a day frees the kingdom in eleven.

3

They arrive ahead, not behind

Every single day ends with a preview of NEXT year's math, so the first week of school feels like territory they've already visited.

The books

Pick the year they just finished.

Each book is a complete 52-page quest: the full curriculum of the finished grade - every topic, every classic misconception - plus a daily head start on the grade ahead.

Peek inside

See a real quest day for yourself.

Straight from the books, unedited - one page from each end of the line. Every grade gets its own edition color: indigo, forest, burgundy.

Book 1 Day 1 gate battle page: the story, the battlefield, the spell, and two attacks to choose from

Day 1 · The Gate Battle

Book 1 · Indigo (grade 3 → 4): story → battlefield → the spell → PICK YOUR ATTACK. Two roads to one victory, because choosing a strategy IS the thinking skill.

Book 3 Fog Fortress bonus page from Grouping Gorge: three optional challenge strikes ending with a 6th grade preview

The Fog Fortress · Bonus Page

Book 3 · Burgundy (grade 5 → 6): always optional, genuinely challenging - three strikes against Lord Muddle, ending with next year's math, borrowed early.

The real curriculum underneath

Five guides teach five thinking skills - the ones that outlast any worksheet.

Each companion trains a research-backed thinking move. Kids earn power chips for honest effort - initialed by you, never for right answers - and their strongest power becomes their hero's animal aspect.

Why kids actually do it

Because it doesn't feel like review. It feels like a boss fight.

Here's the secret your child never needs to know: every villain in Mathedonia is a real math misconception. The Scrambler reads "3 + 2 × 4" left to right like a book. The Factor Faker swears the factors of 6 are "6, 12, 18..." Your child doesn't just answer questions - they catch the boss's exact wrong idea and prove it wrong.

Wrong answers never cost anything: "the boss blocked that attack - switch roads and strike again." That's productive struggle, dressed as combat.

The finish line

Finish the quest, and a real foil hero card arrives in the mail.

The motivation engine that carries kids through all eleven days: inside every book, your child designs their own hero card. Finish the quest, and that design becomes a professionally-made foil trading card - their name, their art, their powers - mailed to your door.

Free all eleven cities

Every boss defeated, every stone of Lord Muddle's HP struck through.

Design the hero card

Your child draws themselves as Mathedonia's new hero.

Email them in on Hero Card Day

Once a season, every finished hero's design becomes a foil card, mailed out together.

For the skeptical grown-up (good - stay skeptical)

The method is boring. The costume isn't.

Strip away the fog villains and here's what's left: the best-evidenced techniques in math education, applied page by page. That's the whole trick - rigor in a costume kids choose to wear.

Metacognition, embedded

Thinking-about-thinking woven into a subject is one of education's best-evidenced boosters - up to +7 months of extra progress in a year (Education Endowment Foundation).

Two attacks per battle

Every fight offers two roads to the answer. Comparing strategies and self-explanation are the two most validated math techniques we know of.

The Singapore path

Pictures before number-sentences: concrete, pictorial, abstract. The challenge pages carry genuine Singapore-level difficulty.

Your job is 30 seconds a day

Initial the effort chips, call out times-table facts when asked, and let your child teach YOU - the protege effect is the deepest learning in the book.

Every answer machine-verified. Every page teacher-reviewed and kid-tested. If your child finishes the quest and doesn't ask what kingdom comes next, we haven't done our job.
Eleven days. That's the whole ask.

Trade one summer of worry for eleven days of adventure.

Pick the grade your child just finished. The kingdom - and the new school year - will take care of the rest.
