8 painted wooden cubes in a wooden box with a lid. The box is hinged and opens out to display the cubes. The lid is printed with the binomial square pattern. Each box contains color coded blocks; One red cube a³, One blue cube b³ Three red and black blocks “a²b” Three blue and black blocks “ab²” The algebraic expression represented is : (a + b)³ = (a + b)(a + b)(a + b) = a³+3a²b+3ab²+b³ Purpose: Introduced at around 3-4 years of age, the purpose of the material is not to teach maths, but instead, to provide a challenge for a child's ability to find patterns and relationships. Therefore, the material is presented as a sensorial activity. The Binomial is used in the primary years to understand and experience algebraic concepts.
