Teen Boards Activity Set
Made by Nienhuis Montessori · shipped by Heutink International (Netherlands) About the maker
Tangible to conceptual, this Teen Boards Activity Set puts children in direct contact with the decimal system through the formation of numbers 11-19. The wooden storage box contains sliding number cards (1-9) that overlay the '10' tile, demonstrating how teen numbers are constructed. The included colored bead chain with a green marker provides concrete counting practice, reinforcing the abstract numerical concepts through hands-on manipulation.
“The senses, being explorers of the world, open the way to knowledge.”
The Teen Boards Activity Set bridges the critical gap between understanding single digits and comprehending the decimal system.
- Understanding teen numbers as compositions of 10 plus units
- Mastering the sequence and names of numbers 11-19
- Developing place value awareness through physical manipulation
- Connecting abstract numerals to concrete quantities

By physically sliding number cards 1-9 over the fixed '10' tile, children witness how teen numbers are literally built from ten plus a unit. This wooden storage box with its precise sliding mechanism transforms an abstract mathematical concept into a tangible experience. The Teen Boards specifically address the developmental need for understanding place value through movement and visual clarity. The colored bead chain with green marker provides essential verification - children count concrete beads to confirm the abstract numbers they've formed on the boards. This dual approach of the Teen Boards, combining numeral construction with quantity counting, respects how young minds grasp mathematical relationships through repeated sensorial experiences. The wooden box's organized compartments ensure each sliding card remains accessible, enabling independent practice as children internalize the pattern of teen number formation.

How to present it
Follow the Montessori method of presentation for optimal child development.
Place the Teen Boards on a mat with the '10' tiles visible. Arrange sliding cards 1-9 in order beside the boards. Position the colored bead chain and green marker to the right.
- 1
Demonstrate sliding the '1' card over the zero of the first '10' tile to form 11
Move slowly and deliberately, allowing the child to see the transformation - 2
Count out 11 beads on the chain, placing the green marker after the eleventh bead
Touch each bead as you count to reinforce one-to-one correspondence - 3
Continue with 12, sliding the '2' card and counting 12 beads
Emphasize the pattern: 'ten and two makes twelve' - 4
Invite the child to form 13, first with cards then counting beads
Step back and observe, intervening only if necessary
