Go back to your own memories of introduction of some of the mathematical concepts like square roots, cubes, algebraic expressions etc. How and when did those concepts come into your life?
For a child who is exposed to Montessori environment, the binomial cubes are first a part of sensorial curriculum.
The material comprises of a eight wooden component cubes painted in red, blue and black when put together correctly creates a cube. The box has a lid and hinged sides which makes all of the pieces perfectly fit inside.
During the early years, the child uses this material to understand relationship of patterns of the blocks. It challenges the child to think of three dimensional puzzles
Later, these act as precursor to introducing mathematical concepts of algebra and fractions. Hence, they experience a wide range of algebraic expressions in the later years.
The binomial cube is a concrete representation of the algebraic formula (a+ b)3.
The factors of the equation are represented by the cubes and prisms.
