Tens Boards in a child's hands
The Tens Boards introduce children to the decimal system through hands-on manipulation of sliding number panels that reveal sequential numbers from 10 to 99. This essential Montessori mathematics material builds concrete understanding of two-digit numbers and place value through visual and tactile exploration. The wooden construction and precision-printed numbers create a durable learning tool that supports the transition from physical to theoretical mathematical thinking.
Decimal System Understanding
Builds concrete foundation for place value and the base-ten system through visual and tactile exploration.
Sequential Number Recognition
Develops ability to recognize and order two-digit numbers through systematic revelation of number sequences.
Fine Motor Coordination
Sliding panels require precise finger movements, strengthening pincer grip and hand control.
Mathematical Order
Introduces patterns in number sequences and prepares for skip counting and mental mathematics.
How to present it
Place the Tens Boards on a table mat with the first board showing 10-19 and the second board nearby. Ensure all sliding panels move smoothly and numbers are clearly visible.
- 1Begin with the first board set to show '10'. Point to each digit and name: 'One ten and zero units makes ten.'
- 2Slide the units panel to reveal '11'. Say: 'One ten and one unit makes eleven.'
- 3Continue sliding to reveal each number sequentially, naming each: '12, 13, 14...'
- 4At '19', demonstrate moving to the second board: 'Now we have two tens.'
- 5Continue through all boards systematically, allowing the child to predict the next number
3 tips for parents
- Notice two-digit numbers in daily life: house numbers, calendar dates, page numbers in books
- Count objects in groups of ten at home: blocks, crayons, or snacks to reinforce tens grouping
- Play 'number detective' games finding specific two-digit numbers in your environment

Frequently Asked Questions
What exactly are the Tens Boards and how do they work?
The Tens Boards are two wooden boards with printed numbers 10-90 in the left column and sliding wooden strips numbered 1-9 that slide over to create all numbers from 10-99. Children physically slide the number strips to reveal and create two-digit numbers, providing a hands-on way to understand place value and the decimal system.
At what age should children begin using the Tens Boards?
Children typically begin using the Tens Boards around age 4-5, after mastering numbers 1-10 and showing readiness for larger numbers. The material is designed for ages 3-6, but the exact timing depends on each child's individual development and prior experience with Montessori math materials like the Number Rods and Spindle Boxes.
What mathematical concepts do children learn from this material?
The Tens Boards teach place value, the decimal system, number sequencing from 10-99, skip counting by tens, and the relationship between tens and units. Children develop a concrete understanding of how two-digit numbers are formed and learn to recognize number patterns, preparing them for more advanced mathematical concepts.
How does this material differ from traditional number charts?
Unlike static number charts, the Tens Boards provide interactive, hands-on learning through moveable number strips that children physically manipulate. This tactile experience creates deeper understanding as children construct numbers themselves rather than simply viewing them, following Montessori's principle of learning through movement and sensorial exploration.
What activities can children do with the Tens Boards beyond basic counting?
Children can practice skip counting by tens, find specific numbers when asked, identify number patterns, match quantity with symbols using golden beads, play number sequence games, and create their own number combinations. Advanced activities include using the boards with other Montessori math materials for operations like addition and subtraction.
