The 9 boxes are 9 math skills. Every day you try each one — but each box moves at its own pace, based only on how you're doing in that specific skill.
Each box has 5 stages:
🟤 Foundation — day 1–30 · getting the basics down
🟢 Developing — day 31–70 · building consistency
🔵 Proficient — day 71–120 · solid and steady
🟣 Advanced — day 121–160 · pushing further
⭐ Mastery — day 161–200 · earns a star
Moving forward: get 3 problems right in a row on a box → jump ahead 3 days in that skill's stage.
If it's tough: you get 3 tries per problem. Miss all 3 attempts three times → the box locks for today and drops back 5 days, but "Practice mode" opens right away so you can keep working on it with no pressure and unlimited tries.
⭐ Mastery: reach day 161+ on a box and you earn a star. Earn all 9 stars and — with your teacher's OK — you move up a whole grade level. Mastered boxes still get a quick daily check-in to stay sharp.
Personalized problems: every problem is generated for exactly where you are — and if you've recently mixed something up (like a symbol, or a specific kind of mistake), your next problems are built to target that gap directly.
