The Fair Spinner
Lakshmi brings her new board game to the veranda, sure her spinner is perfectly fair because all eight slices are the same size. Chitra agrees the slices match, but fair is about the colours. Counted together: red four, blue three, yellow one, and green none at all. So Lakshmi rebuilds it herself, two slices for every colour, and sixteen fair spins land close, but not equal.
For parents: Probability: we count the chances first, in slices, and then we can say what is more likely, what is less likely, and what can never happen. More slices, more likely. No slices, never. A fair spinner gives every colour the same number of slices, so every colour has the same chance, and fair never promised equal tallies.

For Parents and Teachers
Ganita House stories teach good math, slowly and properly. Each story carries one idea, and the idea is always estimated, proven, and checked backwards before Chitra says her favourite word: Proven.
- One idea per story. Counting in tens, fair sharing, patterns, fractions.
- Watch or read. Every episode has a comic version on its story page, plus a problem to try together and an off-screen activity.
- No accounts for children. The only signup on this site is the weekly digest, and it is for grown-ups.
