Small Number Cards 1-9000: Plastic
Made by Nienhuis Montessori · shipped by Heutink International (Netherlands) About the maker
These durable plastic Small Number Cards introduce children to the decimal system through independent work of numbers 1-9000. The color-coded design follows Montessori principles with green units, blue tens, red hundreds, and green thousands, so children can build and understand multi-digit numbers through visual and tactile manipulation. Essential for developing place value comprehension and preparing for advanced mathematical operations.
“The senses, being explorers of the world, open the way to knowledge.”
The Small Number Cards 1-9000 embody Montessori's belief that children construct mathematical understanding through manipulation of concrete materials. These plastic cards with their distinctive color coding, green units, blue tens, red hundreds, and green thousands, make the abstract concept of place value visible and tangible.
- Understanding place value through color-coded decimal categories
- Building and reading numbers from 1 to 9000
- Recognizing the hierarchical structure of the decimal system
- Developing number composition and decomposition skills

When children physically overlay a blue 40 card with a green 3 card to create 43, they experience the decimal system's hierarchical structure through their hands. The cards' systematic progression from 1 to 9000 respects the child's need to explore number relationships independently. Unlike static number representations, these moveable cards allow children to build, deconstruct, and reconstruct any number within their range, fostering deep comprehension of how our number system operates. The color-coding system provides immediate visual feedback about place value categories, enabling children to self-correct as they work with increasingly complex numbers.
How to present it
Follow the Montessori method of presentation for optimal child development.
Arrange cards in columns by place value: units (1-9) in green on the right, tens (10-90) in blue, hundreds (100-900) in red, and thousands (1000-9000) in green on the left. Place each category in sequential order.
- 1
Introduce units first, having the child arrange green cards 1-9 vertically
Let the child discover the pattern of single digits - 2
Add tens column, showing how 10, 20, 30 progress with zeros
Emphasize the zero as a placeholder - 3
Demonstrate overlaying: place 40 on the mat, then slide 3 partially over it to show 43
Keep the first digit of each card visible when overlaying - 4
Invite child to build specific numbers like 256 using appropriate cards
Start with 2-digit numbers before progressing to 3 or 4 digits - 5
Challenge child to build numbers you say aloud: 'Please make 3,847'
Observe which place values they select first
