Teen Bead Box: Individual Glass Beads 10-19 for Decimal System
Made by Nienhuis Montessori · shipped by Heutink International (Netherlands) About the maker
A box of coloured bead bars one to nine and nine golden ten bars in glass, for use with the teen boards. Glass beads are what this version buys: they are heavier than nylon, they click rather than clatter, and a child laying out ten and three feels the ten as the substantial thing it is. The colour code is the same one the child will meet in every later bead material, so nothing here has to be relearned. Wood, glass beads and wire, for ages 3 to 6.
“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.'”
The Teen Bead Box embodies Maria Montessori's principle of concrete to abstract learning, where children physically manipulate beautiful glass beads to understand the composition of teen numbers. This material bridges the critical gap between single-digit numbers and the decimal system, allowing the child to see and feel that teen numbers are composed of a complete ten plus units. The sensorial experience of handling the smooth glass beads engages multiple senses, creating neural pathways that support mathematical understanding.
- Understanding teen number composition (10 + units)
- Linear counting skills from 10-19
- Visual discrimination of quantity differences
- Foundation for place value comprehension

Through repeated exploration, children develop what Montessori called 'materialized abstractions' - concrete experiences that later transform into abstract mathematical thinking. The organized presentation in compartments respects the child's need for order and supports their mathematical mind's natural tendency to classify and categorize.
How to present it
Follow the Montessori method of presentation for optimal child development.
Place the Teen Bead Box on a mat. Have the teen boards (11-19) ready nearby. Ensure the child knows numbers 1-10 and can identify the golden ten bar.
