Free number bonds game for Years 1 to 3 — bonds to 10, 20 and 100, matched to the national curriculum. No account needed.
Build fast, flexible recall of number pairs that total 10, 20 or 100 in calm untimed practice or a short optional sprint. Correct answers can trigger celebrations. Feedback and retry options depend on the game.
Learning objective: Recall and use addition and subtraction facts within 20, then apply the same structure to complements to 100.
Curriculum anchor: England mathematics programmes of study: number, addition and subtraction in Key Stage 1 and lower Key Stage 2.
This game is designed as short independent practice after an idea has been introduced. It does not replace direct teaching, mathematical or scientific discussion, or an adult checking whether the learner can explain the idea away from the screen.
Ask the learner to explain how a bond to 10 can be scaled or adjusted to make a bond to 20 or 100. Take a break when you need one.
