Subtraction Strip Board (Nienhuis) in a child's hands
A board for the subtraction tables from one to eighteen, worked with natural wooden strips whose lengths match the squares. One strip covers the part being taken away and a second marks where to read the answer, so the child is not remembering a fact but constructing it and seeing the result sit in the row. Doing every combination this way is what turns the tables from something recited into something a child could rebuild if they forgot. Wood with laminated paper, for ages 3 to 6.
Mathematical Understanding
Builds concrete understanding of subtraction through visual and tactile manipulation of quantities.
Pattern Recognition
Children discover mathematical patterns and relationships between numbers through systematic exploration.
Concentration
The methodical process of working through subtraction combinations develops sustained focus and attention to detail.
Abstract Thinking
Bridges the gap between concrete manipulation and abstract mathematical concepts, preparing for mental arithmetic.
How to present it
Place the Subtraction Strip Board on a mat with the blue and red strip boxes arranged by size. Position the blank equation cards and pencil to the right.
- 1Select an equation card (e.g., 9-4). Place the blue 9-strip at the board's left edge
- 2Count 4 spaces from the right end of the blue strip and place the red 4-strip
- 3Read the answer where the red strip begins on the number line
- 4Record the complete equation (9-4=5) on paper
- 5Return strips to their boxes and select a new equation
3 tips for parents
- Practice identifying 'take away' situations in daily life before introducing the board
- Allow repetition of favorite equations - mastery comes through repeated exploration
- Avoid rushing to mental math; the physical manipulation builds essential understanding

Frequently Asked Questions
What age is the Subtraction Strip Board appropriate for?
The Subtraction Strip Board is designed for children ages 3-6 years old. However, it's most commonly introduced around age 4-5 when children have mastered basic counting and have experience with the Addition Strip Board.
How does the Subtraction Strip Board help children learn?
The board provides a hands-on, visual method for understanding subtraction. Children physically manipulate color-coded strips on a numbered grid, making abstract subtraction concepts concrete. This helps them discover patterns, memorize subtraction facts, and develop deep mathematical understanding through repetition.
What materials are included with the Subtraction Strip Board?
The set includes a wooden board with a numbered grid from 1-18, a complete set of blue and natural wooden strips in varying lengths representing different numbers, and a wooden storage box. Some versions also include control charts for self-correction.
Do children need prior experience before using this material?
Yes, children should have a solid understanding of numbers 1-20, experience with counting backwards, and ideally have worked with the Addition Strip Board first. They should also understand the concept of 'taking away' through practical life activities.
How long do children typically work with the Subtraction Strip Board?
Children usually work with this material over several months, progressing from simple equations to memorizing all subtraction facts up to 18. Daily practice of 15-20 minutes helps children internalize the subtraction tables and recognize mathematical patterns.
