Tangrams are probably the least expensive but the most powerful set of manipulatives in the teacher’s mathematical toolbox. Tangrams can be used for teaching geometry at any grade level.

Even fractional problem solving at an algebraic level can be taught with this simple manipulative. Tangrams can be fun, fun, fun.
