A cube composed of 27 wooden blocks which fit together in a trinomial pattern, forming a concrete representation of the the algebraic formula (a + b + c)3. Each face that is "a2" is red, "b2" is blue, and "c2" is yellow and all other faces are black.

The factors of the equation are represented by the colour coded cubes and prisms. Younger children can explore the Trinomial Cube as a sensorial activity of visual discrimination of color and form. This can serve as an indirect preparation for algebra and mathematics.
