8 painted wooden cubes and rectangular prisms 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.
Educational Purpose:
This material visually and physically represents the algebraic identity:
(a+b)3
It helps children understand the concept of volume and the relationship between cube components and algebraic expressions. Each piece corresponds to a term in the expansion of (a+b)3, allowing learners to build a concrete foundation for algebra through hands-on exploration.
