This is a box containing 27 high precision solid wooden cubes in a natural finish with purpose-designed box that allows all sides to open out flat permitting unhindered access to the cubes. The silkscreen printed control chart on the lid is a practical and convenient means of using this item. This material is a concrete representation of the trinomial formula (a + b + c)3 . It also serves to encourage perception of mathematical patterns and is an indirect preparation of the child to algebra.
