About

The Addition Strip Board provides a concrete visual and tactile method for children to explore addition facts up to 18. Using color-coded blue and red wooden strips, children physically combine quantities on the numbered grid, discovering patterns in addition while developing their mathematical reasoning and memory of basic facts.

The Montessori Method

The Addition Strip Board transforms abstract number relationships into tangible experiences through color-coded wooden strips that children physically manipulate on a numbered grid. This mathematical manipulative board addresses the young child's need to understand addition through movement and visual patterns, allowing them to build equations with blue and red strips while discovering mathematical relationships independently. The board's design with its precise grid up to 18 enables children to explore all possible addition combinations systematically, creating a sensorial foundation for memorizing addition facts. By physically placing strips end-to-end on the numbered grid, children internalize the concept that addition means combining quantities to create a new total. The Addition Strip Board's concrete approach honors the child's developmental stage where hands-on manipulation precedes abstract understanding, providing repeated opportunities to discover that 5+3 and 3+5 both equal 8 through direct experience with the colored wooden strips.

✹Masters addition facts from 1+1 through 9+9 through hands-on manipulation✹Discovers commutative property by observing that 4+2 equals 2+4✹Develops visual memory of number combinations through color patterns✹Builds systematic thinking by exploring all possible ways to make each sum✹Strengthens fine motor control through precise placement of strips on grid

Activity Guide

Step by Step to Mastery

5 steps to mastery

Blue always goes first to establish consistent left-to-right progression

Ensure strips touch without overlapping for accurate sum reading

Run your finger along both strips to reinforce the combining action

Say the equation aloud while writing to engage multiple senses

Try all combinations that equal the same sum to discover relationships

Developmental Benefits

Why Educators Choose This

Addition Fact Memorization

Systematic work with the strip board helps children discover and internalize all addition combinations that sum to 18 or less.

Pattern Recognition

Children identify mathematical patterns such as commutative property and number bonds through hands-on exploration.

Visual-Spatial Understanding

The grid layout with emphasis at 10 supports understanding of base-ten system and develops spatial number sense.

Fine Motor Precision

Placing strips accurately on the grid refines pincer grip and hand-eye coordination essential for later writing.

Begin with combinations of 10 or less before expanding to sums up to 18

Create equation booklets for children to complete systematically with the board

Observe which facts children struggle with and offer targeted three-period lessons for these combinations

Pro Tip

“Introduce after the child has worked extensively with the Number Rods and understands quantities 1-10”

Frequently Asked Questions

Everything you need to know about this material.

Contact Our Experts

What age is the Addition Strip Board suitable for?

The Addition Strip Board is designed for children ages 3-6 years old, though it's most commonly introduced around age 4-5 when children have mastered one-to-one correspondence and can count to at least 10.

How does the Addition Strip Board teach addition?

Children place blue and red wooden strips on a numbered grid to physically combine quantities. For example, to solve 5+3, they place a blue strip covering 1-5 and a red strip covering 6-8, visually seeing that together they reach 8.

What's included with the Addition Strip Board?

The set includes a wooden board with numbered grid from 1-18, 9 blue wooden strips (representing numbers 1-9), 9 red wooden strips (also 1-9), and typically comes with a wooden storage box for organizing the strips.

What mathematical concepts does this material teach?

Beyond basic addition facts, children discover commutative property (3+5=5+3), explore number bonds, recognize patterns in sums, and build a concrete foundation for memorizing addition tables up to 9+9.

How is this different from traditional addition teaching methods?

Unlike abstract worksheets or flashcards, the Addition Strip Board provides hands-on manipulation where children physically see and feel quantities combining, making abstract addition concepts concrete and memorable through sensorial experience.
