5 wooden boxes with lids contain triangles in different sizes, shapes and colors.
This set is about 30% smaller than the full-sized Constructive Triangles.
The purpose of this product is to introduce the child the concept that visual images may be combined to create different visual images. Indirectly, to prepare the child for later work in Mathematics, by demonstrating the principle that allplane geometric figures constructed with straight lines may be conceived as being composed of triangles.
