Spot the congruent twin (same shape and size), the similar scaled copy, or the odd shape out.
Congruent shapes are the same shape AND size; similar shapes are the same shape at a different scale — and the child sorts them by finding the exact twin, the scaled copy, or the odd one out. Comparing shapes across rotation and size builds congruence and similarity. Best for Grades 3–5.
A free, no-signup, no-ads math game for Grades 3–5 — practising congruence, similarity, shape-recognition, scaling, transformations. Play in your browser on the KidsDoMath games hub or explore more Geometry & Shapes games.
