Geometric Hierarchy of Number in a child's hands
The number cards of the Geometric Hierarchy of Number are a Montessori set with the numerals 1, 10, 100, 1,000, 10,000, 100,000 and 1,000,000. A wooden storage box is included. Each numeral is ten times the one before it, so the child can lay the cards in a row from the unit up to the million and follow the steps of the decimal system. After the work the cards go back into the wooden box and stay together. The set weighs 90 g and is meant for children aged 6 to 12.
Mathematical Foundation
Introduces the geometric hierarchy of numbers through color-coding, preparing for advanced decimal system work.
Visual Discrimination
Color-coded system helps children distinguish between units, tens, hundreds, and thousands.
Order and Sequence
Sliding tile system develops understanding of numerical order and place value relationships.
How to present it
3 tips for parents
- Notice your child's interest in counting objects at home, this indicates readiness for this material
- Support by using consistent color language when available (green for ones) but don't force connections
- Celebrate the process of sliding and arranging rather than focusing on numerical outcomes

Frequently Asked Questions
What is the purpose of the Geometric Hierarchy of Number material?
This material introduces children to place value and the decimal system through color-coded number tiles. It helps children visually and tactilely understand that numbers are composed of units, tens, hundreds, and thousands, with green representing units in the Montessori color-coding system.
How do children use this number card holder?
Children take the number cards out of the wooden storage box and lay them out in order. They can arrange and rearrange the cards to explore number relationships, practice recognizing place values, and build a concrete understanding of the hierarchical nature of our number system.
What makes this a Sensorial material rather than Mathematics?
While it introduces mathematical concepts, this material is classified as Sensorial because it focuses on visual discrimination and tactile exploration of the geometric properties of numbers. It prepares the child's senses for later abstract mathematical work by providing concrete, color-coded representations.
What age is appropriate for this material?
This material is designed for children ages 3-6 years. It's typically introduced after children have worked with other sensorial materials and have developed fine motor control. The material bridges sensorial work with early mathematical concepts.
How does this material prepare children for future math work?
By introducing the color-coding system (green for units, blue for tens, red for hundreds), this material prepares children for the golden bead material and other decimal system work. It creates a visual and tactile foundation for understanding place value before children work with larger numbers.
