7 Best Montessori Trinomial Cubes

best montessori trinomial cubes

The Montessori trinomial cube is a classic Montessori math toy that allows children to explore algebraic concepts. This guide will cover what trinomial cubes are, their benefits for kids, the best ages to introduce them, how to use the cubes and the mathematical concepts they teach. We also listed some of the top-rated Montessori trinomial cubes that you can purchase.

What Are Montessori Trinomial Cubes?

Montessori trinomial cubes consist of a set of small cubic blocks that attach together to form one large cube. Each set includes three different colors of cubes, with 1 unit, 10 units, and 100 units for each color.

The small cubes represent the algebraic trinomial equation:

a3 + b3 + c3 = (a + b + c)3

By physically building the cubes together, children can see how the sum of the small cubes mathematically relates to the large cube. This creates a hands-on understanding of algebraic concepts.

Why Should Kids Use Montessori Trinomial Cubes?

The cubes make abstract formulas tangible, allowing children to gain firsthand experience with algebraic concepts appropriate for their age. Working with trinomial cubes provides many developmental benefits for children:

  • Introduces algebraic thinking in a concrete, hands-on way
  • Let children discover mathematical relationships through exploration
  • Develops spatial awareness and geometric thinking skills
  • Refines fine motor control and coordination
  • Allows practice sorting by color, shape, and size
  • Fosters concentration and logical reasoning skills
  • Helps kids gain independence and self-confidence

What Are the Best Ages for Montessori Trinomial Cubes?

Trinomial cubes are generally introduced in Montessori classrooms around age 6 or 7. However, kids as young as 4 or 5 can explore the basic sorting and stacking activities.

Younger children enjoy sorting the cubes by color and fitting them together. As mathematical skills advance, usually around age 6, kids become ready to understand the algebraic relationship. Guided lessons on the formula around this age provide the ideal introduction. You can view the formula below, which can be helpful when trying to teach kids how the cubes work.

How Does the Montessori Trinomial Cube Formula Work?

The trinomial cube formula demonstrates how:

a3 + b3 + c3 = (a + b + c)3


  • a, b, and c represent the sides of each small cube
  • a3, b3, and c3 signify cubing those sides to find the volume of the small cubes
  • (a + b + c) represents the sum of the sides of the large cube
  • Cubing this side gives the volume of the large cube

So the algebraic formula shows that the total volume of the small cubes equals the volume of the large cube. Physically building the cubes lets children experience this relationship concretely.

How to Use the Montessori Trinomial Cubes

There are many ways for kids to explore the cubes:

  • Sort cubes by color, size, and shape
  • Stack cubes into towers or pyramids
  • Fit cubes together to build the large cube
  • Count the number of cubes at each size
  • Add the volumes by counting cube units
  • Take cubes apart and rebuild them
  • Verbally identify the relationship between the small and large cubes

Adults can guide children through the activities by asking questions and introducing new vocabulary. Hands-on manipulation of the cubes lets kids discover mathematical connections.


Montessori trinomial cubes allow children to see algebraic formulas take shape by physically manipulating the blocks. This hands-on approach lays the foundation for abstract mathematical thinking and problem-solving. The cubes provide an engaging, developmentally appropriate introduction to early algebraic concepts.
