MathKidoo
Your ten fingers, opened into a hundred.
Maths your child can SEE.
Built in India for ages 5–12.
Touch 4 × 6

Four rows, six across. The rectangle floods with colour and the count is the answer: 24.
Chanting tables isn't knowing tables.

Fear of maths starts at 7
Speed drills before understanding break confidence.
The method
Ten is a column.
Add · the hop
Down the column, one ball at a time. At the foot: "column full — that is a ten." The carry teaches itself.
Times · the train
One train of four cars, ten stops, never back to the station. "Three fours are 12" — and 12 stays gold.
Share · which stop?
The same train, parked. "Which stop is this?" 28 is stop 7.
Take · the hop back
Up the column. Crossing the top borrows a ten — the same picture, run backwards.
The same table, again, as rows.
Width fixed at four, rows added one per stop. The running total on the left is the table; the fixed 4 on the right never changes.

Why this becomes inevitable
- 1
Every child already owns the model — ten fingers, opened into a hundred. - 2
One picture carries all four operations. - 3
The carry, the borrow and the ten are SEEN before they are named. - 4
It runs on the phone the family already has, offline, twenty minutes a day, sound off. - 5
Speed is the last gate, so it is the anxious child's method too.
What we have proved, and what we haven't.
The method is built on established learning science, and we can show you the paper. What we have not done is run the controlled trial that would let us say it beats chanting. That trial is designed and it is next. Until it reports, we will not claim it — and you should be wary of anyone who does.
No ads. No chat. No data sold. 20-minute daily screen governor built in.
A child's app that respects childhood.
Questions parents ask
What age is it for?
Children of 5 to 12. The Tables Package starts at counting; the ladder runs to Class 6 arithmetic.
Does it work offline?
Yes. Once the app has opened, everything learnt works with no internet.
Can we use it with the sound off?
Yes. Every spoken line is also a caption, and every move is shown on the field.
One phone, many children?
Up to four child profiles on one parent login, each with their own field and progress.
Can our school use it?
Yes — seats from launch at ₹99–149 per child per year, with a counts-only class view.
What is charged today?
Nothing. MathKidoo is free while we launch, and no card is taken.
