This set contains four cubes dissected four different ways to form a variety of geometric solids. The instructions contain seven brain teasers in which different three-dimensional geometric shapes are formed with the pieces. This puzzle makes use of the fact that the face diagonal and space diagonal of a unit cube are the squares roots of 2 and 3, respectively, to introduce students to the concept of irrational numbers. Three reproducible worksheets cover the history of the square root of 2, the discovery of irrational numbers, and the Pythagorean Theorem. Contains 11 geometric solids made from soft, durable, and nontoxic foam. Cubes measure 2.5" on a side.
