Ages 5–8 · place value dojo
Eight games and three illustrated lessons that turn the trickiest part of early maths — teen numbers, place value and carrying the one — into a ninja belt you earn.
🎓 Learn the secrets
Most early maths trouble isn't arithmetic — it's these three ideas going unsaid. Each one gets its own hands-on lesson before any game asks about it.
Fourteen and forty‑one sound like cousins and get mixed up for years. The lesson slows the words right down so the difference becomes obvious — and audible.
The Number Machine has three houses. Fill the ones house past nine and ten cubes visibly bundle into a rod and move next door. Nobody has to be told the rule.
"Carrying" is just trading ten smalls for one big because the house is full. Once that lands, regrouping addition stops being a memorised dance.
🎮 Play & earn stars
Every correct answer is a star. Five in a row opens a mystery chest with a ninja friend inside. Tap any game to jump straight in.
🥋 The belt ladder
Stars add up to belts. The bar on the home screen always shows how many stars are left to the next one — the reason to do "just one more round".
