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

Soft Sensory Baby Cube with Bell

A Montessori-inspired sensory baby cube for infants 0–9 months that supports early development through sound, touch, and visual exploration. This soft fabric block encourages grasping, hand–eye coordination, and tummy-time play. 

The photos show two sides of the same cube. The bear side includes crinkle foil for a gentle rustling sound when pressed, while the lion side remains soft and quiet. This purposeful contrast gives babies two distinct experiences — one that stimulates auditory curiosity and cause-and-effect learning, and one that offers a calm tactile focus.

This material is used for calculating volume and complements the Cubing Material. It consists of a wooden box with a hinged lid containing 1,000 uniform wooden cubes, each measuring 1 cm. 

The activity helps the child gain a concrete understanding of volume by filling a defined space with identical cubes.

The Volume Box contains 250 wooden cubes in a wooden box with lid. 

This material is used to demonstrate and calculate volume by filling a defined space with uniform cubes. It helps the child make a concrete association with the concept of volume.

 Recommended for ages 6 to 9, as part of the Montessori Elementary curriculum.

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.
