Maths you can see, from counting to calculus.
Every sum starts as a picture, gets worked out step by step, then practised until it sticks. For a seven-year-old learning to count, or a grown-up who never quite got percentages.

Not worksheets. Games that teach.
Story Quest
Story sums set around Chennai: idlis in Mylapore, mangoes at Koyambedu, passengers on the Metro. Guess first, then solve one step at a time.
Mistake Detective
Kutty has slipped up somewhere in this working. Find it, name it, fix it, and stop making it yourself.
Picture It
Type any sum and watch it happen: ones bundle into tens, columns carry, long division plays out.
Table Turbo
One times table at a time, with dot pictures and tricks, then race the clock. A heat map shows what’s shaky.
Know what to practise next.
