Tangram Block Set

A classic for a reason - these sturdy, floor sized felt blocks are perfect for spatial reasoning puzzling and practice with flexible symbolic representation. One of the oldest versions of a dissection puzzle; a master shape, in this case a square, is dissected into smaller shapes that are then rearranged to create additional puzzles. Simply, and directly demonstrating the mathematical relationship between basic shapes and 45 degree angles, these special shapes flexibly rearrange to illustrate geometric principles of right triangles and ratio concepts of scale and proportion.

Includes the 7 necessary tangram shapes and 23 durable pattern cards, featuring both an easy and hard version of each build target.

2 large triangles

1 medium triangle
