Subtracting within 10 worksheet

Part A: Working out and filling in

1. 1. 7 − 2 = 5

   Ask "2 plus what makes 7?", 2 + 5 = 7, so it's 5

2. 2. 5 − 5 = 0

   Ask "5 plus what makes 5?", 5 + 0 = 5, so it's 0

3. 3. 10 − 9 = 1

   Ask "9 plus what makes 10?", 9 + 1 = 10, so it's 1

4. 4. 4 − 1 = 3

   Ask "1 plus what makes 4?", 1 + 3 = 4, so it's 3

5. 5. 10 − 2 = 8

   Ask "2 plus what makes 10?", 2 + 8 = 10, so it's 8

6. 6. 9 − 6 = 3

   Ask "6 plus what makes 9?", 6 + 3 = 9, so it's 3

7. 7. 5 − 4 = 1

   Ask "4 plus what makes 5?", 4 + 1 = 5, so it's 1

8. 8. 4 − 3 = 1

   Ask "3 plus what makes 4?", 3 + 1 = 4, so it's 1

9. 9. 6 − 3 = 3

   Ask "3 plus what makes 6?", 3 + 3 = 6, so it's 3

10. 10. 4 − 2 = 2

    Ask "2 plus what makes 4?", 2 + 2 = 4, so it's 2

11. 11. 9 − 8 = 1

    Ask "8 plus what makes 9?", 8 + 1 = 9, so it's 1

12. 12. 8 − 1 = 7

    Ask "1 plus what makes 8?", 1 + 7 = 8, so it's 7
