Teen Boards: US Version
Made by Nienhuis Montessori · shipped by Heutink International (Netherlands) About the maker
The Teen Boards introduce children to the decimal system and the formation of numbers 11-19 through hands-on manipulation of wooden number panels. This essential Montessori mathematics material features sliding wooden boards with clearly printed black numerals that combine to create teen numbers, supporting the concrete understanding of place value and number composition. The US version ensures alignment with American educational standards while maintaining authentic Montessori methodology.
“The child is both a hope and a promise for mankind.”
The Teen Boards serve as a bridge between single-digit recognition and the abstract understanding of the decimal system, addressing the critical developmental need for concrete manipulation of number concepts. These wooden panels with sliding number boards allow children to physically construct teen numbers, making visible the mathematical principle that teen numbers are composed of ten plus a unit.
- Understanding that teen numbers are composed of 10 plus units 1-9
- Recognizing and reading numerals 11-19 in sequence
- Developing concrete understanding of place value
- Building foundation for addition with tens

The Teen Boards' design, featuring clearly printed black numerals on smooth wooden surfaces, enables children to discover independently that 11 through 19 are not arbitrary symbols but logical combinations following a pattern. Through repeated manipulation of these sliding boards, children internalize place value concepts that would remain abstract if presented only verbally. The US version of the Teen Boards maintains precise number formation while aligning with American educational practices, ensuring seamless integration with subsequent mathematical work.
How to present it
Follow the Montessori method of presentation for optimal child development.
Place the Teen Boards on a mat with the first board showing 10. Have the unit cards 1-9 ready in order. Ensure child knows numerals 1-10 and has worked with the golden bead material.
- 1
Show how to slide the unit card '1' over the zero in 10 to make 11
Move slowly and deliberately, allowing the child to see the transformation - 2
Say 'eleven' clearly as you form the number, then remove the unit card to show 10 again
Emphasize the word 'eleven' rather than 'ten-one' to introduce proper nomenclature - 3
Continue with 12, sliding the '2' card while saying 'twelve'
Let the child predict what comes next before showing each new number - 4
After demonstrating 11-13, invite the child to form 14
Watch for correct card placement, the unit must completely cover the zero - 5
Work through all numbers to 19, then practice in random order
Return to sequential order if child struggles with random presentation
