The Constructive Triangles give the child practical experience in plane geometry. They are called “constructive” because the child sees the triangle as the element which forms other rectilinear figures.
5 wooden boxes with lids contain triangles in different sizes, shapes and colors: a rectangular box containing 14 triangles, a triangular box containing 10 triangles, a small hexagonal box containing 18 triangles, a large hexagonal box containing 11 triangles, a rectangular box containing 8 blue triangles.
