Found Montessori Binomial Cube

The Montessori Binomial Cube is a classic sensorial and early algebra material designed to help children physically explore the mathematical formula: (a + b)³ = a³ + 3a²b + 3ab² + b³.

While children first experience it as a 3D puzzle, this beautiful wooden box introduces the foundation of binomial expansion — years before they study algebra formally.

Recommended Age:

3.5 – 6 years (Sensorial introduction)

6+ years (Early algebra concept)

How to Use:

1. Sensorial Exploration

The child removes and reassembles the 8 wooden blocks into the original cube shape, using visual matching of colors and shapes.

2. Visual Pattern Recognition

This Cube for (a + b)³ provides the basis necessary for the sensorial construction of higher powers of the same binomial:

(a + b)⁴and (a + b)⁵

This cube represents the equation  (a + b + c)³  in concrete form and differs from the Trinomial Cube in that the component pieces are color-coded to represent hierarchical values from 1 unit to 1 million.

This makes it possible for the child to equate an arithmetical value to each of the cubes and prisms.

The Power of 3 Cube consists of a dissected cube in 13 pieces painted yellow, green and white.

Demonstrates the power of 3 by progressively tripling the previous piece, starting with a two centimeter cube. That cube is then triples with two similar cubes. Those three cubes are then tripled with two 6 x 2 x 2 centimeter prisms, eventually creating an 18 centimeter cube.

The wooden tray is included.

The Power of 2 Cube demonstrates the power of two with cubes and prisms, each one squared from the previous. 

It comes in a hinged wooden box with lid.

Ages: 6-9

Great for walking or building!

There are 3 different patterns providing different levels of tactile stimulation.

 The bottom side has three anti-slip rubber discs to provide traction.

The cubes can also be connected to construct different 3-D structures, especially when combined with the Reflector Cubes and Construction Tower. Includes an instructional booklet.
