Let’s work through each subtraction problem using the “doubles” strategy shown in the worksheet.
The idea is:
If you know a doubles fact (like 2 + 2 = 4), you can use it to subtract.
For example:
4 – 2 = ? → Think: 2 + 2 = 4 → So, 4 – 2 = 2
✔
We’ll do the same for each one.

Problem 2: 8 – 4 = ?
Think: What doubles fact has 4?
→ 4 + 4 = 8
So, if 4 + 4 = 8, then 8 – 4 =
4
✔ Check: 4 + 4 = 8 → Correct.
---
Problem 3: 10 – 5 = ?
Think: What doubles fact has 5?
→ 5 + 5 = 10
So, 10 – 5 =
5
✔ Check: 5 + 5 = 10 → Correct.
---
Problem 4: 12 – 6 = ?
Think: What doubles fact has 6?
→ 6 + 6 = 12
So, 12 – 6 =
6
✔ Check: 6 + 6 = 12 → Correct.
---
Problem 5: 6 – 3 = ?
Think: What doubles fact has 3?
→ 3 + 3 = 6
So, 6 – 3 =
3
✔ Check: 3 + 3 = 6 → Correct.
---
All answers are now filled in using the doubles strategy.
Final Answer:
2: 4
3: 5
4: 6
5: 3
