The Montessori Binomial cube consists of a total of 8 blocks where each block represents the equation- a^{3}+ 3a^{2}b+ 3b^{2}a+b^{3}.

## What does the Montessori Binomial Cube Incorporate?

The binomial cube consists of:

- 1 red-colored cube
- 3 black and red prisms
- 3 black and blue prisms
- 1 blue cube

These pieces are stored in a wooden box with a colored pattern painted on it.

The pattern of the lid of the box matches the patterns of the blocks inside the box.

## What is the aim of the Montessori Binomial Cube?

- The main aim of the Montessori binomial cube is to help the child understand the spatial relationship.
- The child will be able to visually discriminate between colors, patterns, and shapes.
- The child will be familiarized with the concept of the Montessori Binomial cube.
- The Montessori Binomial cube has manufactured control of error that helps the child understand the concept independently.

## How to Present the Montessori Binomial Cube to the child?

It is mandatory to introduce the name of the activity or material before inviting the child to participate in the activity.

- Ask the child to carry the Binomial Cube Material with both hands and place it on the table.
- Place the Binomial cube box on the upper left side of the table with the pattern side facing towards you.
- Take the lid from the box and lace the side that fashions the pattern towards the child.
- Show the child the matching patterns presented on the lid and the cube.
- Take the lid off from the box and one by one take out the blocks from the box.
- Starting from the blue cube begin to create the first layer of the cube in front of the child.
- Then show the matching pattern of the bottom layer on the lid of the box.
- Like the top layer of the cube, rebuild the bottom layer in front of the child.
- Then form a new column with blocks forming the bottom layer, starting with a red block and keeping the other blocks in their orientation.
- Put the blocks in the left column moving from left to right and then from the top to bottom, starting with the red blocks. Make sure the pattern matches the lid.
- Once you are done with this activity, place each cube one by one back into the Montessori Binomial Cube box.
- Then indicate the pattern of the cube imprinted on the box and on the lid is the same.
- Repeat the activity with the top layer, forming a column and making a matching pattern on the lid.
- Then transfer the new column to the finished binomial cube.
- Indicate that the cube and the lid have the same pattern.
- Fold the sides of the box and invite the child to participate in the Montessori Binomial Cube activity.

## Montessori Trinomial Cubes

The Montessori Trinomial cube is introduced after the Binomial cube. The Montessori Trinomial Cube is similar to the Binomial Cube but represents the trinomial algebraic equation- (a+b+c)^{3}.

It is a unique Montessori Sensorial Material that represents complex mathematical equations to elementary children in a concrete and tangible form.

This material is introduced to children in the second year of the Montessori Primary program. With the help of the Montessori Trinomial Cube, the child is able to visually discriminate between different shapes, sizes, and colors.
