Let's solve the addition problems using a
number line, as instructed in the worksheet.
Step-by-step Explanation:
The number line goes from 0 to 10:
```
<---0 1 2 3 4 5 6 7 8 9 10--->
```
To add two numbers using a number line:
1. Start at the first number.
2. Move forward (to the right) by the number of steps equal to the second number.
3. The number you land on is the answer.

Now, let’s solve each problem:
---
1. 6 + 1 = ?
Start at 6, move 1 step forward →
7
2. 6 + 2 = ?
Start at 6, move 2 steps forward →
8
3. 3 + 3 = ?
Start at 3, move 3 steps forward →
6
4. 5 + 3 = ?
Start at 5, move 3 steps forward →
8
5. 2 + 4 = ?
Start at 2, move 4 steps forward →
6
6. 3 + 4 = ?
Start at 3, move 4 steps forward →
7
7. 7 + 2 = ?
Start at 7, move 2 steps forward →
9
8. 6 + 3 = ?
Start at 6, move 3 steps forward →
9
9. 2 + 2 = ?
Start at 2, move 2 steps forward →
4
10. 3 + 2 = ?
Start at 3, move 2 steps forward →
5
11. 4 + 4 = ?
Start at 4, move 4 steps forward →
8
12. 1 + 4 = ?
Start at 1, move 4 steps forward →
5
13. 4 + 3 = ?
Start at 4, move 3 steps forward →
7
14. 7 + 4 = ?
Start at 7, move 4 steps forward →
11
Wait! But the number line only goes up to 10.
So,
7 + 4 = 11, which is
beyond the number line shown. However, we can still calculate it:
7 + 4 =
11

Final Answers:
```
6 + 1 = 7
6 + 2 = 8
3 + 3 = 6
5 + 3 = 8
2 + 4 = 6
3 + 4 = 7
7 + 2 = 9
6 + 3 = 9
2 + 2 = 4
3 + 2 = 5
4 + 4 = 8
1 + 4 = 5
4 + 3 = 7
7 + 4 = 11
```
✔ All answers are correct based on addition principles, even though 11 goes beyond the number line.

Summary:
- Use the number line to count on for each sum.
- Each time, start at the first number and jump forward by the second number.
- Practice helps build number sense and mental math skills.
