About This Product
Rebuilding the square, or making patterns and designs with all 7 pieces, has students rotate, flip and slide shapes both in their heads and on the desk. That practice feeds straight into lessons on congruent and similar figures, symmetry and area, since every arrangement made from one set has the same total area. The plastic pieces are durable and easy to clean.
