The binomial cube is useful for the development of the mathematical mind. It consists of a cube-shaped box with two hinged sides to which hinges are attached to allow a special opening. The cube contained in the box is made up of eight geometric solids: two cubes; three rectangular parallelepipeds with the same shapes; three rectangular parallelepipeds. The cube helps to understand the algebraic formula (a+b)3 sensorially.

Age: from about four years. The box is made of birch wood and the cube is made of beech wood. The game is a visual, tactile and muscular memory aid, facilitates abstraction and prepares for algebra.
