Fill rows of unit squares, fold the triangle from its rectangle, slice-and-slide the parallelogram — build every area.
Given a triangle or parallelogram, the task alternates between calculating area from a known base and height, and working backward to find a missing base when the area is provided. Repeated practice sharpens area formulas and the relationship between a shape's dimensions. Best for Grades 4–6, or any child who is comfortable with multiplication and ready to apply it to geometry.
A free, no-signup, no-ads math game for Grades 4–6 — practising area, triangles, geometry. Play in your browser on the KidsDoMath games hub or explore more Measurement games.
