📚 Part 1: Warm-up Multiple Choice

WALT: We Are Learning To use number lines to subtract.

Success criteria: I can draw a number line, count backwards in jumps and write the correct answer.

1. Start at 15 on the number line. Subtract 7. Where do you land?

2. On a number line, subtraction is usually done by:

counting forwards (to the right)

counting backwards (to the left)

staying still

3. Start at 30. Subtract 12. What is the result?

✏️ Part 2: Short Answers — Use a Number Line

4. 15 − 7 = Draw jumps on the number line below and write your answer.

5. 34 − 18 = Draw jumps showing tens and ones. Write your answer.

6. 72 − 25 = Use a number line: first jump back 20, then jump back 5. Show your jumps and answer.

7. 100 − 47 = Show how you would count back on a number line (you may jump in tens then ones).

8. 142 − 36 = Use a number line to solve. Draw the jumps and write the answer.

🔎 Part 3: Extension & Teacher Notes

9. Extension: Create your own subtraction problem (two jumps) and show it on the number line. Problem: ___________ Answer: ___________

10. Explain in one sentence: How can you check a subtraction answer using addition? (e.g., to check 72 − 25 = 47)

Differentiation strategies: Provide pre‑labelled number lines for students with dyscalculia; give extra spacing and pastel paper for students with dyslexia; allow counters or a floor number line for hands‑on support. For higher achievers, ask them to make and solve three-step subtraction problems on a number line.

Dyslexia-friendly reading options: Use large clear font, extra line spacing and pastel backgrounds; read problems aloud and allow oral responses where needed.

Extension activity (quick): Pair with a peer and explain the jumps you made on your number line. Try converting your subtraction into an addition check.
