Geometric Hierarchy Of Number in a child's hands
The green cube with a 5 mm edge is a single wooden piece of the geometric hierarchy of number, which shows the numbers 1, 10, 100, 1,000, 10,000, 100,000 and 1,000,000 in geometric form. The cube is the smallest piece and stands for the unit. According to Nienhuis the material makes it possible to compare the decimal categories by size and to show decimal value through colour. The cube is made of beech and is green. The other pieces of the material are not included.
Mathematical Visualization
Provides concrete representation of units, helping children understand abstract number concepts through physical manipulation.
Spatial Reasoning
Develops understanding of three-dimensional relationships and how units combine to form larger quantities.
Foundation for Powers
Introduces the concept of exponential growth as children see how units build into bars, squares, and cubes.
Fine Motor Precision
Small size requires careful handling, refining pincer grasp and hand control essential for later writing.
How to present it
Place a small tray with 10-20 green cubes on a mat. Have the complete hierarchy materials nearby but initially focus only on the unit cubes.
- 1Invite the child to count out exactly ten green cubes, placing them in a line
- 2Show how ten cubes can form different arrangements - a line, scattered, or stacked
- 3Build a square using multiple cubes, counting as you place each one
- 4If available, compare the built square to the hundred-square from the hierarchy
3 tips for parents
- Practice counting small objects at home (beans, pennies) to reinforce one-to-one correspondence
- Point out groups of ten in everyday life: fingers, toes, eggs in some cartons
- Support patience by celebrating process over speed when counting or arranging objects

Frequently Asked Questions
What is the purpose of this 5mm green cube in Montessori mathematics?
This green cube represents a single unit (1) in the Montessori Geometric Hierarchy of Number system. It serves as the foundation for understanding place value, powers of ten, and how numbers grow geometrically. Children use it to build larger numbers and visualize mathematical relationships concretely.
How does this cube work with other Geometric Hierarchy materials?
The 5mm green cube is part of a complete system where 10 units form a ten-bar, 10 ten-bars form a hundred-square, and 10 hundred-squares form a thousand-cube. This progression helps children physically experience how numbers grow by powers of ten and understand place value through hands-on manipulation.
What skills does working with this material develop?
This material develops spatial reasoning, mathematical visualization, fine motor control, and concrete understanding of abstract number concepts. Children learn one-to-one correspondence, counting, place value, and begin to understand the decimal system through physical manipulation of these precise geometric forms.
Do I need to purchase multiple cubes or the complete set?
While one cube can introduce the concept of a unit, the material is most effective when used as part of the complete Geometric Hierarchy set or with multiple units. Having at least 10 cubes allows children to build a ten-bar equivalent and truly understand the relationship between units and larger numbers.
