To solve the problem, we need to analyze each number line and determine the addition sentence that corresponds to it. The number lines show jumps starting from 0 and ending at a specific point, which represents the sum of two numbers.

Step-by-Step Solution:

#### 1st Number Line:
- The number line shows a jump from 0 to 2, and then another jump from 2 to 4.
- This indicates the addition: \( 2 + 2 = 4 \).

#### 2nd Number Line:
- The number line shows a jump from 0 to 3, and then another jump from 3 to 5.
- This indicates the addition: \( 3 + 2 = 5 \).

#### 3rd Number Line:
- The number line shows a jump from 0 to 1, and then another jump from 1 to 3.
- This indicates the addition: \( 1 + 2 = 3 \).

#### 4th Number Line:
- The number line shows a jump from 0 to 1, and then another jump from 1 to 3.
- This indicates the addition: \( 1 + 2 = 3 \).

#### 5th Number Line:
- The number line shows a jump from 0 to 1, and then another jump from 1 to 4.
- This indicates the addition: \( 1 + 3 = 4 \).

#### 6th Number Line:
- The number line shows a jump from 0 to 2, and then another jump from 2 to 5.
- This indicates the addition: \( 2 + 3 = 5 \).

Final Answers:

1. \( 2 + 2 = 4 \)
2. \( 3 + 2 = 5 \)
3. \( 1 + 2 = 3 \)
4. \( 1 + 2 = 3 \)
5. \( 1 + 3 = 4 \)
6. \( 2 + 3 = 5 \)

Boxed Answer:

\[
\boxed{
\begin{array}{ccc}
2 + 2 = 4 & & 3 + 2 = 5 \\
1 + 2 = 3 & & 1 + 2 = 3 \\
1 + 3 = 4 & & 2 + 3 = 5 \\
\end{array}
}
