🔹 Strategy: "Make a 10"
We look for two numbers that add up to
10, then add the remaining number.
Let’s go through each problem:
---
1. 6 + 4 + 8 = ?
- First,
6 + 4 = 10 → we make a 10.
- Then,
10 + 8 = 18
-
✔ Answer:
18
> Circle:
6 and 4 → makes 10
---
2. 5 + 8 + 2 = ?
- Look for a pair that makes 10:
8 + 2 = 10
- Then,
5 + 10 = 15
-
✔ Answer:
15
> Circle:
8 and 2 → makes 10
---
3. 4 + 5 + 5 = ?
-
5 + 5 = 10
- Then,
4 + 10 = 14
-
✔ Answer:
14
> Circle:
5 and 5 → makes 10
---
4. 3 + 7 + 9 = ?
-
3 + 7 = 10
- Then,
10 + 9 = 19
-
✔ Answer:
19
> Circle:
3 and 7 → makes 10
---
5. 2 + 8 + 3 = ?
-
2 + 8 = 10
- Then,
10 + 3 = 13
-
✔ Answer:
13
> Circle:
2 and 8 → makes 10
---
6. 7 + 9 + 1 = ?
-
9 + 1 = 10
- Then,
7 + 10 = 17
-
✔ Answer:
17
> Circle:
9 and 1 → makes 10
---
7. 4 + 7 + 3 = ?
-
7 + 3 = 10
- Then,
4 + 10 = 14
-
✔ Answer:
14
> Circle:
7 and 3 → makes 10
---
8. 5 + 5 + 8 = ?
-
5 + 5 = 10
- Then,
10 + 8 = 18
-
✔ Answer:
18
> Circle:
5 and 5 → makes 10
---
9. 7 + 3 + 2 = ?
-
7 + 3 = 10
- Then,
10 + 2 = 12
-
✔ Answer:
12
> Circle:
7 and 3 → makes 10
---
10. 6 + 1 + 9 = ?
-
6 + 1 = 7, but better:
1 + 9 = 10
- Then,
6 + 10 = 16
-
✔ Answer:
16
> Circle:
1 and 9 → makes 10
---
✔ Final Answers:
| Problem | Answer |
|--------|--------|
| 6+4+8 | 18 |
| 5+8+2 | 15 |
| 4+5+5 | 14 |
| 3+7+9 | 19 |
| 2+8+3 | 13 |
| 7+9+1 | 17 |
| 4+7+3 | 14 |
| 5+5+8 | 18 |
| 7+3+2 | 12 |
| 6+1+9 | 16 |
