Power Blocks (tangrams) In Stock Now

A set of Power Blocks consist of 254 blocks cut in the shape of triangles, squares, rectangles, and parallelograms. They are produced in several different colors, that may be mixed or left intact when in use. Two or three sets is a useful quantity for a class of 30, depending on the activity planned. One reason for leaving the sets intact is to facilitate whole class instruction. Frequently within a class, each group of students needs the large blocks to solve a problem. There are fewer of the larger shapes than the smaller shapes. Having each set a different color enables the teacher and students to locate missing blocks quickly. 

Power Blocks are cut to metric units. The basic unit of length is the length of the side of the smallest square, which is 25 mm. Each of the different pieces are inscribed with a code to identify it. Each set of Power Blocks has within it all the pieces required to make four separate Tangram Puzzles, including 100 square tiles. 

The shapes have been designed around the pattern for the powers of two (1, 2, 4, 8, 16, 32, etc.). 

There is also a teacher's idea book available for check-out.
