Moyo Montessori Subtraction Strip Board is an illustrative mathematics aid for children aged 5 and over, making it easier to understand subtraction, number combinations, and relationships between numbers. Using colorful wooden strips, children can practically explore examples within the range of 1 to 18.
The Montessori Subtraction Strip Board offers a clear and illustrative way to introduce children to subtraction. The board has 216 squares arranged in 12 columns and 18 rows. The number sequence from 1 to 18 is color-coded: numbers 1–9 are blue and numbers 10–18 are red.
The aid includes colorful wooden strips for working with numbers and natural wooden strips for covering unused numbers. Children can easily cover numbers, observe the subtraction result, and gradually learn all possible combinations. The aid builds on knowledge of the Montessori subtraction snake game and is suitable for guided work at home, in preschool, or at school.
