Arithmetic Trinomial Cube

Item# 018700   This cube represents the equation (a + b + c)³ in concrete form and differs from the Trinomial Cube in that 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. Contained in a hinged wooden box with lid.
