Vito has perfected the Montessori Binomial Cube and I will be introducing him to the Trinomial cube in a few weeks. Now, I still have a lot of readers and followers who aren’t aware of this beautiful material and has been asking me to give them further information about this material. So I prepared this post to all who are interested in learning about this beautiful Montessori sensorial material.
What is Montessori Binomial Cube?
The Montessori Binomial Cube is introduced as a sensorial material on early childhood aged kids (3-6) and as a math material in the elementary level. It composed of 8 blocks, 2 cubes of red and blue and the remaining blocks has red and black, blue and black patterns. They are contained in a wooden box with a lid that has a pattern shown below.
Benefits
The aim of using Binomial Cube is further develop the visual perception of the child in 3-dimensional objects, and at the same time, indirectly prepare him/her for future work on Mathematics (algebra).
For what age?
This is introduced as sensorial material for 3 years old+ . It is used to match the colors and patterns (as a puzzle) to improve visual discrimination.
As math to form the cube of binomial (a+b)3, at 8 years old and older.
How to Use Binomial Cube as Sensorial Material
Name the Binomial Cube to the child and show where it is placed. I usually ask my child “Do you want to play the Binomial Cube?” if he answers yes, the ask your child to fetch the Binomial Cube and place it on your work table. Start the presentation by gently raising the lid, showing and describing the contents. One by one, take out the prisms and place it in a similar manner as shown in the picture. One column for the blue cube and blue-black prisms and the red cube and red-black prisms.
Now let’s build the Binomial Cube! Using the pattern on the lid, place the 2 red-black prisms around the red cube with red faces touching any of the red faces of the red cube.
One the first layer of the pattern is made, you can move it to the box. For the next one, start by placing the red-black prism on the lid with the red face touching the red mark on the lid. Now place the blue-black prisms around the red-black prism with the black faces touching the black face of the red-black prism. To complete the pattern, place the blue cube with its face touching the blue faces of the blue-black prisms. Move it to the top of the first set of prisms in the box.
Gently close the hinges of the box and cover with the lid. Note to the child the pattern in the constructed Binomial Cube inside the box is the same pattern shown on the lid.
