First 2 Strips For Addition / Subtraction Strip Board in a child's hands
The first two strips for the addition and subtraction strip board, in red, blue and natural, are sold as replacement pieces. According to Nienhuis the addition board uses red strips divided into squares and solid blue strips with the numerals 1 to 9, and the subtraction board uses natural wooden strips and blue strips. The child lays the strips along the rows of squares and reads the result. The strips are made of beech. The boards and the remaining strips are not included.
Mathematical Foundation
Builds concrete understanding of addition and subtraction through physical manipulation of numbered strips.
Visual Discrimination
Color-coding helps children distinguish between mathematical operations and organize their work systematically.
Fine Motor Control
Precise placement of strips on the board develops hand control and coordination essential for later writing.
Abstract Thinking
Bridges the gap between concrete manipulation and abstract mathematical concepts through repeated practice.
How to present it
Place the Addition or Subtraction Strip Board on the work mat. Arrange the red strips 1-9 vertically on the left side, blue strips 1-9 on the right side. Keep natural strips available for extended work.
- 1For addition: Select any red strip (first addend) and place it starting from the left edge of the board
- 2Choose a blue strip (second addend) and place it directly after the red strip with no gap
- 3Read where the blue strip ends on the numbered board to find the sum
- 4For subtraction: Place a blue strip at the number being subtracted from (minuend)
- 5Place a red strip from the left edge to show what's being subtracted
- 6Record the equation on paper using the strip numbers and result
3 tips for parents
- Practice simple addition at home using rulers or paper strips cut to specific lengths
- Ask your child to show you equations using their fingers as 'strips' during daily activities
- Celebrate when your child discovers patterns like 'all ways to make 10' through strip exploration

Frequently Asked Questions
What are these strips used for in Montessori mathematics?
These wooden strips are essential components of the Montessori Addition and Subtraction Strip Boards. Children use them to physically represent numbers and construct mathematical equations, making abstract concepts concrete through hands-on manipulation.
Why are there three different colors of strips?
The red strips typically represent the first addend or minuend, blue strips represent the second addend or subtrahend, and natural strips can be used for answers or additional practice. This color-coding helps children visually distinguish between different parts of mathematical operations.
Do I need the Strip Board to use these strips?
Yes, these strips are specifically designed to work with the Montessori Addition and Subtraction Strip Boards. The boards provide the structured grid and guidelines necessary for proper use of the strips in mathematical exercises.
What skills do children develop using these strips?
Children develop number sense, understanding of quantity, addition and subtraction concepts, fine motor skills, concentration, and the ability to work independently. The strips also prepare children for mental math by providing concrete experiences with number relationships.
How many strips are included in this set?
This set includes the first 2 strips for use with Addition/Subtraction Strip Boards. For complete work with these boards, you'll need full sets of strips numbered 1-9 (and sometimes 1-18 for addition), which are typically purchased separately or as complete sets.
