Tens Boards Activity Set in a child's hands
An essential classroom resource, this Tens Boards Activity Set guides discovery of place value concepts through hands-on manipulation of numbered cards. The wooden storage box contains specially designed cards showing numbers in both digit and word form, where children build two-digit numbers while understanding the relationship between tens and units. A strong fit for developing mathematical foundations through concrete materials that make abstract number concepts visible and tangible.
Mathematical Understanding
Builds concrete understanding of place value and the decimal system through hands-on manipulation
Language Development
Connects number symbols with written words, reinforcing mathematical vocabulary
Sequential Thinking
Develops logical ordering skills as children arrange numbers from 1-99
Fine Motor Control
Precise card placement refines pincer grasp and hand-eye coordination
How to present it
Remove the wooden box lid and place it beside the box. Arrange the tens cards (10, 20, 30...90) in order on the left side. Place unit cards (1-9) in sequence on the right.
- 1Invite the child to build the number 11 by selecting the '10' card and placing the '1' card on top, aligning it to cover the zero
- 2Continue building 12, 13, through 19, naming each number as you construct it
- 3Build 20 by removing all unit cards and selecting the '20' tens card
- 4Invite the child to continue building numbers sequentially or to construct specific numbers you name
3 tips for parents
- Practice reading two-digit numbers in everyday life - house numbers, calendar dates, page numbers
- Point out groups of ten in collections: 'You have twenty marbles - that's two groups of ten!'
- Support your child's work by providing uninterrupted time to explore number patterns

Frequently Asked Questions
What age is the Tens Boards Activity Set appropriate for?
The Tens Boards Activity Set is designed for children ages 3-6 years old. It's particularly effective when children have already worked with quantities 1-10 and are ready to explore larger numbers and place value concepts.
How does this material teach place value?
The set uses visual cards that separate tens and units, allowing children to physically build two-digit numbers by combining cards. This concrete manipulation helps children understand that numbers like 34 are made of 3 tens and 4 units, making abstract place value concepts tangible.
What's included in the wooden storage box?
The set includes numbered cards showing digits 10-90 in tens, unit cards 1-9, and corresponding word form cards. All materials are organized in a wooden storage box with compartments for easy access and proper storage after use.
Do children need prior number knowledge before using this?
Yes, children should be familiar with numbers 1-10 and have experience with concrete counting materials like the golden beads or number rods. This foundational knowledge helps them understand the progression to tens and place value.
How does this differ from traditional number teaching methods?
Unlike abstract number teaching, this Montessori material allows children to physically construct numbers, see the separation between tens and units, and match digit forms with word forms. This multi-sensory approach creates deeper understanding through hands-on exploration.
