Binomial Cube

The Binomial Cube is a three-dimensional puzzle that represents the algebraic equation (a + b)³. It consists of eight wooden blocks of varying colors and sizes that fit together within a hinged wooden box. The purpose of this material is to introduce children to the concept of binomial expansion in a concrete, visual way. It also helps develop their spatial awareness, fine motor skills, and problem-solving abilities as they learn to assemble the cube.
