Join two groups and count them all — the very first idea of adding. Ready?
Before a child can learn any clever addition trick, they need to know what addition is: you take two groups of things, put them together, and count them all to find how many there are altogether. For 3 + 2, you gather three balls and two balls into one pile and count "one, two, three, four, five" — five altogether. This "count all" idea is the foundation the whole addition staircase is built on.
The game starts completely concrete — two groups of jelly balls you can see and touch — and fades the help away over six short steps until the child can add the numbers in their head:
That last step is the whole point: once the groups get big, counting every single ball one by one is tiring — and that is exactly when a child is ready for the next trick, counting on, where you start from the bigger number instead of counting from one.
Class 1 children (ages 5–7) just starting addition, including the CBSE/NCERT addition-within-20 expectations. Every instruction is spoken aloud, so pre-readers can play alone, and the game remembers where your child reached.
