Stamp Game Activity Set
Made by Nienhuis Montessori · shipped by Heutink International (Netherlands) About the maker
Exercise cards with divider tabs in a wooden box, extending the stamp game. The stamp game is where a child does a four digit operation alone for the first time, and the thing that then limits them is not skill but supply: somebody has to keep producing problems. These cards remove that adult from the loop, which is the whole point of the material, since an operation you chose yourself and checked yourself is worth more than twenty an adult handed you. Stamp game sold separately. Wood, cardstock and paper, for ages 3 to 12.
“Free the child's potential, and you will transform him into the world.”
The Stamp Game Activity Set bridges concrete mathematical manipulation and abstract number work through its color-coded cards that correspond directly to the Stamp Game's place value system.
- Master place value concepts through color-coded visual organization
- Perform multi-digit addition and subtraction with increasing accuracy
- Develop systematic problem-solving approaches for mathematical operations
- Build confidence transitioning from concrete materials to abstract numbers

Each activity card in this set presents problems specifically designed to isolate one mathematical concept, allowing children to build confidence with multi-digit operations at their own pace. The handcrafted wooden storage box creates an organized system where children can independently select appropriate challenge levels. Unlike random problem sets, these structured cards progress systematically from simple exchanges to complex operations, respecting the child's need for ordered progression. The color-coding on each card, green for units, blue for tens, red for hundreds, provides immediate visual feedback about place value relationships. This activity set recognizes that mathematical abstraction develops gradually; the cards serve as a crucial intermediate step between manipulating stamps and working with written numerals alone.

How to present it
Follow the Montessori method of presentation for optimal child development.
Place the wooden storage box on a mat. Arrange activity cards by difficulty level in separate sections. Have the Stamp Game material ready on an adjacent mat with stamps sorted by place value.
- 1
Child selects an appropriate activity card from their current working level
Start with cards showing problems the child has successfully completed with teacher guidance - 2
Read the problem on the card and lay out corresponding stamps on the Stamp Game board
Encourage reading the entire problem before beginning to prevent rushing - 3
Perform the operation using stamps, making exchanges as needed
Have the child verbalize each exchange to reinforce place value understanding - 4
Record the answer on paper and check using the control card if provided
Model neat number formation to support clear mathematical thinking - 5
Return materials to their proper places before selecting next card
This reset time allows mental processing of completed work
