Adding means “putting together”. In this game kids find which blocks add up to the target — for a target of 5 they can pick 2+3 or 1+4. They discover that a number splits into pairs in many ways (number bonds), the foundation of mental addition.
Block 2 and block 3 = 5
1 and 4 also makes 5 — many ways to make it!
4 and 4 makes 8
💡 For parents
Ask your child to say what they're adding out loud — “two plus three makes five”. Saying it helps the number pairs stick. Start little ones on the easy level (small target, numbers 1–3) and move up. Short 5–10 minute sessions are plenty.
Number bonds — knowing which numbers add up to a given number, like 5 = 1+4 = 2+3. It's the foundation for fast, accurate mental math.
Around 4–7. Younger kids start on the easy level (small target, numbers 1–3, slow drop); older kids can pick levels with bigger numbers and a faster drop.
Yes. The blocks show clear numbers, and the game says the running total aloud as they tap, so kids pick up addition through play without memorising.
