Dial the hidden number of a bond triangle and watch it forge all four related facts at once.
Three numbers make a fact family — the number-bond triangle that forges two addition and two subtraction facts (or two multiplication and two division). The child dials the hidden number and sees all four related facts appear, learning how the operations undo each other. Best for Grades 1–3.
A free, no-signup, no-ads math game for Grades 1–3 — practising fact-families, number-bonds, addition, subtraction, inverse-operations. Play in your browser on the KidsDoMath games hub or explore more Counting & Numbers games.
