About this number bonds game
This free number bonds game helps young kids build the foundational skill of finding the missing number needed to reach 10, 20 or 100 — one of the earliest and most important building blocks in primary maths. Choose which target numbers to include, set your question count and time limit, then find as many missing numbers as you can. Strong number bonds make later addition, subtraction and mental maths much easier.
