Subtraction Strip Board

The Subtraction Strip Board helps children to practice subtraction using a structured format. This material includes a board with numbered strips that children use to perform subtraction operations within the number range 1-18. By placing the strips on the board, children can visualize the process of subtracting numbers. This material consists of: a board divided into squares with the numerals 1-18 printed along the top and a blue vertical line before the 10; a wooden box containing 9 red and 9 blue strips of varying lengths with the printed numerals 1-9; a wooden box containing 17 wooden strips of varying lengths in a natural wood finish.
