Description
This Arithmetic Trinomial Cube is designed to support the child in their deeper exploration of algebra. The Arithmetic Trinomial Cube is a physical representation of the equation (a + b + c)³. Each of the component pieces are color-coded to represent hierarchical values from 1 unit to 1 million. This makes it possible for the child to equate an arithmetical value to each of the cubes and prisms.
The cube is contained in a wooden box with lid and hinged sides.
