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.
