This is a Chinese Tangram Puzzle, and this listing is for a whole classroom set. I sell an accompanying history lesson blurb and 25 design handout as well, when you buy the class set, that handout is free.
The tangram is an excellent crossover education/developmental teaching aid, as it can be used for almost all grades, to stimulate creativity, and teach geometry and even history.
There are various games based on the Tangram, like competing to see who can make a design first. There are over 1000 designs that can be made.
