Montessori Teen Numbers Activities | Hands-On Number Sense, Place Value & Math Printable for Ages 4–7

The teen numbers are often where children first realise that our number system has a pattern.

What may seem simple to adults can feel surprisingly abstract for young learners. Why is 16 called sixteen? Why does the 1 stay the same while the other number changes? Why do teen numbers sometimes get reversed when reading or writing them?

This Montessori-inspired Teen Numbers resource was created to help children move beyond memorisation and truly understand the structure of numbers from 11–19 through meaningful, hands-on exploration.

Rooted in authentic Montessori mathematics principles, these activities support children as they build a concrete understanding of place value, quantity, symbol recognition, and the concept of “ten and some more.” Rather than rushing children through worksheets, this resource encourages deep mathematical understanding through repetition, movement, visual supports, and independent discovery.

As a Montessori educator, I know that strong mathematical foundations are built when children can physically see and manipulate mathematical concepts before moving into abstraction. The teen numbers are a critical bridge between counting and place value, and this material helps children make that connection with confidence.

Perfect for Montessori classrooms, homeschool environments, kindergarten mathematics, early intervention settings, and children who benefit from visual and hands-on learning experiences.

Included in this resource:

• Teen number activities for numbers 11–19
• Place value and quantity matching work
• Number recognition activities
• Counting and symbol association tasks
• Hands-on Montessori-inspired math extensions
• Printable maths shelf work
• Independent learning activities

CONTENTS

- Control chart - poster of teen numbers

- Posters for every number from 10 - 20 with suggestions for a game, a great whole-body activity!

- Matching a picture to the colored bead bars: 3 versions car, cupcake and superhero.

-Colored set of beads for student to match with numeral numbers 10-20

-Colored set of beads with student to match tally marks with numbers 10-20

-4 worksheets where child goes over the numeral, cuts and pastes the colored beads and shows on a tens frame.

- a set of number tiles from 10-20 with colored beads to match the tile to the beads

- a match up game where the child matches the number to the colored beads to a 10 + _ equation

- Practice sheets for you to laminate and the child to complete with equations for numbers for 10 to 20

-4 picture puzzles (penguin, koala, car, rocket)

Supports children with:

• Understanding teen numbers 11–19
• Early place value concepts
• Number formation and recognition
• Counting accuracy
• Quantity-to-symbol matching
• Mathematical confidence
• Independent problem solving
• Building strong number sense foundations

This resource is especially helpful for children who need additional repetition, concrete learning experiences, or visual mathematical support. Many children can recite teen numbers long before they truly understand them. These activities help bridge that gap and create those powerful “I get it!” moments that build lifelong confidence in mathematics.

Montessori mathematics is designed to help children discover patterns, relationships, and logic within numbers. When children understand why numbers work the way they do, mathematics becomes far less overwhelming and far more meaningful.

A thoughtful and engaging Montessori maths resource designed to help children build a deep understanding of teen numbers rather than simply memorising them.
