Let's solve each addition problem using the
number line method. The idea is to:
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 sum.

📌 How to Show on Number Line (Example for 9 + 4):
- Draw a dot at
9.
- Then draw
4 arrows or jumps to the right, each one step.
- End at
13.
You can do this for each problem similarly.
