Stamp Game: Mathematical Operations
Made by Nienhuis Montessori · shipped by Heutink International (Netherlands) About the maker
Part of the Decimal System collection, this classic Montessori Stamp Game transforms abstract mathematical concepts into concrete manipulative experiences through color-coded number tiles representing units, tens, hundreds, and thousands. The wooden compartmented tray organizes plastic tiles and game pieces systematically, giving children the ability to explore the decimal system, perform four operations, and develop a deep understanding of place value through hands-on manipulation.
“Education is a natural process spontaneously carried out by the human individual, and is acquired not by listening to words but by experiences upon the environment.”
The Stamp Game bridges the gap between concrete golden bead material and abstract paper calculations by providing color-coded tiles that children physically manipulate to solve mathematical problems. Each plastic tile in the Stamp Game represents a specific place value - green units, blue tens, red hundreds, and green thousands - allowing children to see and touch the decimal system's structure.
- Understanding place value through color-coded tile manipulation
- Performing addition, subtraction, multiplication, and division with concrete materials
- Developing mental math strategies through physical exchanges
- Recognizing patterns in the decimal system

The compartmented wooden tray organizes these tiles in columns that mirror written mathematical notation, helping children internalize how numbers are composed and decomposed. Through exchanging ten unit stamps for one ten stamp, or ten ten-stamps for one hundred stamp, children discover the hierarchical nature of our number system. The Stamp Game's portable format and individual tiles make it possible for children to work independently with large numbers and complex operations that would be cumbersome with golden beads.
How to present it
Follow the Montessori method of presentation for optimal child development.
Place the wooden tray on a work mat. Arrange tiles in their compartments: green units (1), blue tens (10), red hundreds (100), green thousands (1000). Have operation cards or written problems ready.
- 1
Introduce each tile value by laying out examples: 1 unit = 1, 1 ten = 10, 1 hundred = 100
Let the child feel the weight of holding multiple tiles versus one higher value tile - 2
Build a four-digit number using tiles, arranging them in columns on the mat
Always work from right to left, starting with units - 3
For addition, build both numbers separately, then combine tiles by category
Count each category separately before exchanging - 4
Exchange when any category exceeds 9 tiles (10 units become 1 ten)
Use a small dish to hold tiles during exchanges - 5
Record the final answer by counting remaining tiles in each column
Have the child verbalize each step to reinforce understanding
