Found Montessori Binomial Cube

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

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 

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.

Arithmetic Trinomial Cube (Montessori)

The Montessori Arithmetic Trinomial Cube gives a concrete, hands-on representation of the algebraic identity (a + b + c)³. Unlike the standard Trinomial Cube used in Primary, this Elementary version is color-coded to show the place-value hierarchy from 1 unit to 1 million, helping children connect cubes and prisms with numerical value.

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.

The wooden tray is included.

The Power of 2 Cube demonstrates the power of two with cubes and prisms, each one squared from the previous. 

It comes in a hinged wooden box with lid.

Ages: 6-9
