This activity teaches the child how to build a cube which indirectly prepares him for understanding the binomial formula: (a+b)3.
In this activity the child assembles a three-dimensional puzzle made up of 8 wooden blocks. This puzzle is the physical representation of the binomial formula: (a+b)<sup>3</sup>.  This activity prepares the child to use the [[Trinomial Cube]].  It also indirectly prepares the child to learn Algebra later on.
