Single-digit subtraction is the process of taking away a smaller number from a larger number, where both numbers are between 0 and 9. It helps children understand the concept of "taking away" or "how much is left," which is an essential skill for solving everyday problems and building a foundation for more advanced math.

1. Subtract step by step: Start with a number and count backward to find the difference.
2. Use visual aids: Like fingers, objects, or a number line, to solve subtraction problems.
3. Recognize relationships:Understand how subtraction undoes addition (e.g., if 5 + 2 = 7, then 7 - 2 = 5).

Examples:

1. Using Fingers:
• Problem: "What is 5 - 2?"
• The child starts with 5 fingers up and folds down 2 fingers. They count the remaining fingers: "1, 2, 3."
• The answer is 3.
2. Using Objects:
• Problem: "What is 7 - 4?"
• The teacher places 7 blocks on the table and removes 4 of them. The child counts the blocks left: "1, 2, 3."
• The answer is 3.

By practicing single-digit subtraction, children develop confidence in solving problems involving "taking away" and prepare for more advanced math operations like multi-digit subtraction and mental math!
