Counting On: the addition trick — start big, count up

Counting on is the first real addition strategy a child learns. Instead of counting every object from one, the child starts at the bigger number and counts up by the smaller one: for 8 + 3, you say "eight… nine, ten, eleven" — three little hops instead of eleven separate counts. It is the bridge between counting and true addition, and it is exactly where many Class 1 children get stuck: they can count two groups of objects, but every sum still means starting again from one.

How this game teaches counting on

Most games tell children the trick and drill it. This course makes the child feel why the trick is worth having first. You begin by counting all the balls one by one — and the game counts your taps, so the slowness of counting everything is felt, not explained. Then, mid-count, something happens: the first group fuses into one big ball that already knows its number. Why count it again? Over a few short steps the help fades away:

  1. Count all the balls — and feel how many taps it takes.
  2. Count again — and watch the first bunch become ONE number.
  3. The bunch arrives pre-counted; you choose which number to start from.
  4. The balls fade, step by step, until only the number remains.
  5. Count on along the number line — no balls at all.
  6. A free-choice challenge: count everything, or jump from the bigger number. Your taps are counted either way.
  7. Now you say each next number yourself.
  8. A practice game with stars — and bigger numbers, where counting all is simply unbearable.

Along the way the game asks the two questions that make the strategy stick: "Which number should we start from?" (always the bigger one — and 3 + 8 is the same as 8 + 3) and "How many more did we count?" — because keeping track of the hops is the genuinely hard half of counting on. The final answer is always typed by the child on the number pad; the game never fills it in for them.

Who this is for

Class 1 children (ages 5–7) learning single-digit addition, including the CBSE/NCERT addition-within-20 expectations. It is also the right remedy for an older child who still counts every sum from one. Every instruction is spoken aloud, so pre-readers can play alone. The game remembers where your child reached and resumes from the same step.
