Found Trinomial Cube

The trinomial cube is contained in a wooden box with lid, having two adjacent hinged sides that open out to display 27 wooden component cubes and prisms painted blue, red, yellow, and black.

The box is hinged and opens out to display the cubes. The lid is printed with the trinomial square pattern.

Dimensions: 5.5 x 5.5 x 4 inches

Information:   
The trinomial cube is similar to the binomial cube, but has the following pieces instead: 

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 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 

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
