Watch a parallelogram shear into a rectangle and a triangle become half of one — then dial the area you now understand.
A parallelogram shears into a rectangle and a triangle folds into half of one, so the child sees why area = base × height (and half of it) before dialling the answer for triangles, parallelograms, and trapezoids. Watching the shape transform teaches the formula, not just the number. Best for Grade 6.
A free, no-signup, no-ads math game for Grade 6 — practising area, triangles, parallelogram, trapezoid, base-height. Play in your browser on the KidsDoMath games hub or explore more Measurement games.
