Are the Montessori Sensorial materials familiar to you? In this blog post, I’m going to be introducing the Binomial Cube, a phenomenal Montessori Sensorial tool as well as an introduction to Algebra.

There are eight ways they appeal to the senses: gustatory (mouth), tactile (touch), stereognostic (muscle memory), baric (weight and pressure), olfactory (nose), auditory (ears), visual (eyes), and thermogenic (temperature). After you read this article, come back to see which category the Binomial Cube falls under. The answer is at the end! Read on!

The Binomial Cube

One red cube, three red and black prisms, three blue and black prisms, and one blue cube make up the eight parts of the Binomial Cube. The Binomial Cube is constructed in two stages.

Presentation (Part 1)

1. The child gets the binomial cube from the shelf and places it in front of him/her on a table or on a mat (on the floor).

2. Slowly, take the binomial cube apart, piece by piece. Set them on two columns. One column has all the prisms with red and red cube. The second column has all the prisms with blue as well as the blue cube.

3. Set up the binomial cube lid by the prisms and cubes. The cube building will take place on the lid, one layer at a time. One tip to remember is: “red touches red,” “blue touches blue,” “black touches black.”

4. Start with the red cube for the first layer. On the red square, place it. There are black rectangles on either side of the red square.

5. Take a red and black prism. Rotate it sideways so the black side rests on the black lid rectangle and the red side touches the red cube. Place the other red and black prism on the red cube’s second open side in the same manner.

6. The area with blue on the lid and black on either side is the only one that is left open. Place a single blue and black prism vertically there.

7. The first layer is done! Take it and slowly place the first layer in the box.

Focus

Direct objective: To effectively build the binomial cube.

Indirect objective: An introduction to algebra.

Ages: It is recommended to start at 3 years of age, but I started a few months early with both of my children. I did find that the binomial cube interest has peaked at 3 and 5 years of age.

Printable Binomial Cube

Configuration:

1. Print page 1 once and page 2 three times in color on white cardstock.

Verify that you have printed the lid, three red and black prisms, three blue and black prisms, and one red and blue cube.

2. Cut the six prisms, the lid, and the two cubes.

3. Attach the cubes together with sticky glue. White glue and glue sticks are not something I advise.

4. Enjoy building the binomial cube by following the presentation instructions (above).

Answer to the category question from the first paragraph:

Did you guess which Sensorial category the Binomial cube falls under? Did you guess visual? Did you guess tactile? Well, it’s both, actually! That’s what I love about the Montessori method! There is always more than one use and application to every work.
