Description :-
The Subtraction Strip Board consists of the following components:
1. Subtraction Board: A wooden board featuring a grid of 12 squares by 18 squares, with the numerals 1-18 printed across the top. The grid helps represent numbers visually, aiding the
child in understanding subtraction.
2. Wooden Tray (1): Contains 9 red wooden strips and 9 blue wooden strips, each printed with the numerals 1 to 9. These strips are used for representing the numbers being subtracted and provide visual cues to support the child in performing subtraction operations.
3. Wooden Tray (2): Contains 18 grey-colored wooden strips of varying lengths, each corresponding to the grid squares (from 1 to 18). These strips are used to represent the minuend (the number from which another number is subtracted), and the blue strips represent the subtrahend (the number being subtracted).
The Subtraction Strip Board is designed to help children practice subtraction in a hands-on and visual way, reinforcing their understanding of how subtraction works.

1. Concrete Experience with Subtraction:
o The Subtraction Strip Board provides a concrete method for children to visualize and physically manipulate numbers during subtraction. By placing the blue and red strips on the grid, children can see how one number is subtracted from another.2. Interactive and Visual Learning:
o Using the grid and coloured strips, children can see how the number being subtracted (the subtrahend) fits into the minuend and how the remaining number is visually represented. This makes abstract mathematical concepts more tangible and understandable.3. Understanding Subtraction Equations:
o Children practice solving subtraction problems such as 13 - 8 = ? by placing the corresponding grey strips (representing the minuend) and blue strips (representing the subtrahend) on the grid. The remaining squares help the child count the difference, reinforcing their understanding of the subtraction process.4. Reinforcement of the Subtraction Table:
o By repeatedly using the strips to solve subtraction problems, children becomefamiliar with the subtraction tables from 1 to 18. This practice improves their ability to recall subtraction facts and helps them memorize the subtraction tables more effectively.5. Sensory Learning:
o The child engages all five senses by interacting with the wooden strips, counting the grid squares, and physically manipulating the materials, making the subtraction process more memorable and enjoyable.
6. Preparation for Future Math Learning:
o This material prepares children for primary school mathematics by establishing a solid foundation in subtraction. It also helps develop their ability to solve problems independently and visualize mathematical concepts.7. Fun and Engaging:
o By turning subtraction into a hands-on activity, the Subtraction Strip Board makes learning math enjoyable and encourages children to approach mathematics with curiosity and enthusiasm.
