Geometric Hierarchy Of Number: Green Cube 5 Mm
Made by Nienhuis Montessori · shipped by Heutink International (Netherlands) About the maker
The green cube of the geometric hierarchy of number, 0,5 x 0,5 x 0,5 cm, sold as a single piece. This is the unit the whole hierarchy starts from, and the smallest object in the material: ten of these make the next piece, ten of those the one after, and by the seventh step the same shape is a cube you need two hands for. Losing the first one costs the material its starting point. The complete hierarchy is a separate item.
“The child is both a hope and a promise for mankind.”
The 5mm Green Cube serves as the concrete representation of a single unit in mathematics, allowing children to physically hold and manipulate the smallest building block of our number system.
- Understanding that numbers are composed of individual units
- Developing one-to-one correspondence through counting cubes
- Building spatial awareness through three-dimensional arrangements
- Discovering the relationship between linear, square, and cubic numbers

This tiny wooden cube transforms abstract numerical concepts into tangible reality, enabling young learners to construct their understanding of quantity from the ground up. Through arranging multiple green cubes into lines, squares, and eventually larger cubes, children discover how units combine to form tens, hundreds, and thousands. The precise 5mm dimension ensures that when ten cubes align, they match perfectly with the next hierarchical piece, revealing the mathematical relationships inherent in our base-ten system. This hands-on exploration with the green cube satisfies the child's need to understand 'how many' through direct sensorial experience, building a foundation for later abstract mathematical thinking.
How to present it
Follow the Montessori method of presentation for optimal child development.
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.
- 1
Invite the child to count out exactly ten green cubes, placing them in a line
Ensure precise alignment to demonstrate how ten units create the same length as one ten-bar - 2
Show how ten cubes can form different arrangements - a line, scattered, or stacked
Emphasize that the quantity remains ten regardless of arrangement - 3
Build a square using multiple cubes, counting as you place each one
Let the child discover that 10x10 requires exactly 100 cubes - 4
If available, compare the built square to the hundred-square from the hierarchy
The physical match reinforces the mathematical relationship
