Hundred / Pythagoras Board: Unprinted Wood Tile (1)
Made by Nienhuis Montessori · shipped by Heutink International (Netherlands) About the maker
One unprinted wooden tile for the hundred board and the Pythagoras board, sold as a single piece. The hundred board is a printed board with a box of chips numbered one to a hundred, and this tile is one of those chips without its number: the right size and thickness for the grid, blank on the face. Use it to keep a set complete, or to mark a value your own work needs and the printed set does not have. The boards are separate items.
“Free the child's potential, and you will transform him into the world.”
The unprinted wooden tile represents a fundamental principle in Montessori mathematics education: the concrete manipulation of abstract concepts. This single wooden piece serves as a blank canvas for mathematical exploration, allowing children to physically handle numerical relationships without predetermined symbols. The smooth wood surface of the tile invites touch and movement, essential for young children who learn through their senses. Within the Hundred Board and Pythagoras Board work, each wooden tile becomes a tangible representation of quantity that children can arrange, count, and pattern.
- Understanding one-to-one correspondence through tile placement
- Developing number sequence recognition from 1-100
- Building spatial awareness of numerical patterns
- Strengthening fine motor control through precise tile manipulation

The absence of printed numbers on this tile encourages children to internalize numerical concepts rather than simply matching symbols. As children place these wooden pieces in sequence or create patterns, they build a sensorial understanding of the decimal system. The tile's simple design eliminates distractions, focusing attention on the mathematical relationships being discovered through hands-on manipulation.

How to present it
Follow the Montessori method of presentation for optimal child development.
Place the Hundred Board or Pythagoras Board on a mat. Have a basket containing multiple unprinted tiles alongside printed number tiles if using them for comparison. Ensure adequate workspace for tile arrangement.
- 1
Invite the child to explore one tile, feeling its smooth surface and edges
Allow time for sensorial exploration before introducing mathematical concepts - 2
Demonstrate placing tiles in sequence on the board, counting aloud as you place each one
Move slowly and deliberately, emphasizing the one-to-one correspondence - 3
Show how to create patterns using the blank tiles (every other square, diagonal lines, etc.)
Start with simple patterns before progressing to complex arrangements - 4
Introduce skip counting by placing tiles only on multiples of 2, 5, or 10
Use the blank tiles to physically represent the 'skipped' numbers
