Decimal Stamp Game
Number tiles printed with decimal fractions from one down to 0.000009, used to name decimal combinations and then to add, subtract and multiply with them. Decimals are where the decimal system finally runs in the other direction, and a child who has spent years going up through units, tens and hundreds needs to meet the mirror image as objects before as notation. Placing a tile for a thousandth beside one for a ten is what makes the symmetry visible. Wood with printed numerals, for ages 3 to 6.
“Free the child's potential, and you will transform him into the world.”
The Decimal Stamp Game bridges the child's understanding from whole numbers to decimal fractions through its color-coded wooden tiles representing powers of ten.
- Understanding decimal place value from tenths to millionths
- Performing addition and subtraction with decimal numbers
- Exchanging between decimal place values (10 tenths = 1 unit)
- Reading and writing decimal numbers accurately

Each compartment in the seven-section wooden tray corresponds to a specific decimal place value, from units through millionths, providing concrete representation of abstract fractional quantities. The physical manipulation of these wooden tiles allows children to experience decimal relationships kinesthetically - moving ten thousandths tiles to exchange for one hundredth tile makes decimal conversion tangible. This material's systematic color-coding matches the traditional Montessori decimal system, enabling children who have mastered whole number operations to naturally extend their mathematical thinking into fractional territories. The Decimal Stamp Game transforms the abstraction of decimal notation into a sensorial experience where children can physically build, exchange, and operate with decimal quantities, preparing them for advanced mathematical concepts through concrete manipulation.
How to present it
Follow the Montessori method of presentation for optimal child development.
Place the wooden tray on a mat with compartments arranged from left to right: units, tenths, hundredths, thousandths, ten-thousandths, hundred-thousandths, millionths. Ensure each compartment contains sufficient color-coded tiles.
- 1
Introduce decimal notation by building 3.5 using 3 unit tiles and 5 tenth tiles
Use decimal point card to show proper placement - 2
Demonstrate exchanging 10 tenth tiles for 1 unit tile
Count aloud while moving tiles to reinforce the relationship - 3
Build larger decimals like 24.367 using appropriate tiles from each compartment
Work left to right, emphasizing place value positions - 4
Practice addition: 3.4 + 2.7 by combining tiles and exchanging when necessary
Let the child discover when exchanging is needed
