How to use this worksheet
- Read each problem aloud as a story: "I have 9, I give away 4, how many are left?"
- Warm up with the four problems that take away 1 (2 − 1, 5 − 1, 8 − 1, 9 − 1), then go back to problem 1.
- For the four problems that start at 10, use both hands: fold down the fingers you take away and count the rest.
- Write each answer on the line after the equals sign, then check with the key on page two.
What this worksheet teaches
Every problem starts from a number between 2 and 10 and takes away less than that number, so all answers fall between 1 and 8. Four problems subtract neighbors (5 − 4, 8 − 7, 2 − 1 and 4 − 3), and each gives 1, a small pattern worth pointing out. Every later subtraction, including column subtraction, relies on these facts.
Think addition to subtract
Subtraction is easier when it is turned into a missing-number addition. For 10 − 8, ask "8 and how many more make 10?" The answer, 2, is a number bond to 10. The same works for 9 − 5: 5 and 4 make 9, so the answer is 4. Counting back suits taking away 1 or 2; for 10 − 8 it means eight steps and more chances to slip.
