The Teen Boards introduce children to the decimal system through tactile learning of numbers 11-19. These precisely crafted wooden boards feature recessed compartments holding removable number tiles, where children build teen numbers systematically. An essential Montessori mathematics material that bridges the gap between single digits and larger number concepts.
“The greatest sign of success for a teacher is to be able to say, 'The children are now working as if I did not exist.'”— Maria MontessoriThe Absorbent Mind
The Teen Boards serve as a concrete bridge between the child's understanding of single digits and the decimal system. Through manipulating removable number tiles within recessed compartments, children physically construct teen numbers, making abstract mathematical concepts tangible. The wooden boards' precise design allows children to see how placing a '1' tile beside single digits creates numbers 11-19, revealing the pattern of our decimal system. This systematic building process through the Teen Boards satisfies the young child's need to understand numerical relationships through sensorial exploration. The boards' structured presentation moves from concrete manipulation to abstract understanding, following the child's natural progression in mathematical thinking. By physically creating teen numbers with the removable tiles, children internalize place value concepts before encountering them abstractly. The Teen Boards provide repeated practice with number formation while maintaining the child's interest through hands-on activity.

Use slow, clear pronunciation for number names
Let the child see the transformation happen slowly
Pause between numbers to allow processing time
Observe which numbers they form confidently
Start with contrasting numbers like 11, 15, 18

“Ensure mastery of numbers 1-9 before introducing Teen Boards”
Everything you need to know about this material.
Contact Our ExpertsThe Teen Boards are two wooden boards with printed '10' numerals and slots where children slide single digit tiles (1-9) to form numbers 11-19. This hands-on material helps children physically construct teen numbers, making the abstract concept of place value concrete and understandable.
Children typically begin using Teen Boards around age 4-4.5, after mastering numbers 1-10 and understanding quantity relationships. The material remains useful through age 6 as children deepen their understanding of the decimal system and prepare for more complex mathematical concepts.
Children develop understanding of place value, teen number formation, and the decimal system foundation. They also enhance fine motor skills through tile manipulation, visual discrimination, sequential thinking, and mathematical language while building confidence with two-digit numbers.
The Teen Boards pair perfectly with the Bead Stair for quantity association, Number Cards for symbol recognition, and later with the Tens Boards (20-99). They also complement the Golden Bead Material for decimal system work and prepare children for the Hundred Board.
Made from high-quality wood with smooth finishes, these boards are designed for years of classroom use. Simply wipe clean with a slightly damp cloth and ensure tiles are stored properly. The recessed compartments protect the tiles and keep all pieces organized for long-lasting use.
