Tangrams

Tangrams are ancient Chinese puzzles. A tangram begins with a square which is then cut into seven standard pieces. Each piece is called a tan. In creating a picture, all seven tans must be used; they must touch, but none may overlap.

When tangrams are used in storytelling the storyteller arranges the tans to show the shape of a character in the tale. As new characters or story elements are introduced, the puzzle pieces are rearranged to represent the new character or new element.
