A tangram is a puzzle made up of seven shapes that can be arranged to form many different designs. A tangram has seven pieces: five triangles, one square, and one parallelogram. With this many shapes to work with, the pieces can be assembled into an almost infinite number of different configurations.
Like building blocks, tangrams can teach kids about spatial relationships. They may help kids learn geometric terms, and develop stronger problem-solving abilities. They might even help children perform better on tests of basic arithmetic.
