Number Line Addition | Number Line Worksheets - Free Printable

Problem Description:

The task involves solving number line addition problems. There are two parts to the problem:

1. Part I: Write the number sentence for each of the given number lines.
2. Part II: Draw the number line for each of the following number sentences.

---

Solution:

#### Part I: Writing the Number Sentence for Each Number Line

We need to analyze each number line and determine the starting point, the jump (addition), and the ending point. The number sentence will be in the form:
Starting Point + Jump = Ending Point

##### A.
- Number Line: Starts at 0, jumps to 3, then jumps to 8.
- Analysis: The starting point is 0, the first jump is 3, and the second jump is 5 (since 8 - 3 = 5).
- Number Sentence: \(0 + 3 + 5 = 8\)

##### B.
- Number Line: Starts at 2, jumps to 7, then jumps to 12.
- Analysis: The starting point is 2, the first jump is 5 (since 7 - 2 = 5), and the second jump is 5 (since 12 - 7 = 5).
- Number Sentence: \(2 + 5 + 5 = 12\)

##### C.
- Number Line: Starts at 3, jumps to 6, then jumps to 11.
- Analysis: The starting point is 3, the first jump is 3 (since 6 - 3 = 3), and the second jump is 5 (since 11 - 6 = 5).
- Number Sentence: \(3 + 3 + 5 = 11\)

##### D.
- Number Line: Starts at 4, jumps to 9, then jumps to 14.
- Analysis: The starting point is 4, the first jump is 5 (since 9 - 4 = 5), and the second jump is 5 (since 14 - 9 = 5).
- Number Sentence: \(4 + 5 + 5 = 14\)

##### E.
- Number Line: Starts at 7, jumps to 12, then jumps to 17.
- Analysis: The starting point is 7, the first jump is 5 (since 12 - 7 = 5), and the second jump is 5 (since 17 - 12 = 5).
- Number Sentence: \(7 + 5 + 5 = 17\)

#### Part II: Drawing the Number Line for Each Number Sentence

We need to draw a number line for each given number sentence, showing the starting point, the jumps, and the ending point.

##### A. \(1 + 8 = 9\)
- Starting Point: 1
- Jump: 8
- Ending Point: 9
- Number Line: Start at 1, make a jump of 8 units to reach 9.

##### B. \(2 + 8 = 10\)
- Starting Point: 2
- Jump: 8
- Ending Point: 10
- Number Line: Start at 2, make a jump of 8 units to reach 10.

##### C. \(3 + 8 = 11\)
- Starting Point: 3
- Jump: 8
- Ending Point: 11
- Number Line: Start at 3, make a jump of 8 units to reach 11.

##### D. \(4 + 8 = 12\)
- Starting Point: 4
- Jump: 8
- Ending Point: 12
- Number Line: Start at 4, make a jump of 8 units to reach 12.

##### E. \(7 + 8 = 15\)
- Starting Point: 7
- Jump: 8
- Ending Point: 15
- Number Line: Start at 7, make a jump of 8 units to reach 15.

Final Answers:

#### Part I: Number Sentences
A. \(0 + 3 + 5 = 8\)
B. \(2 + 5 + 5 = 12\)
C. \(3 + 3 + 5 = 11\)
D. \(4 + 5 + 5 = 14\)
E. \(7 + 5 + 5 = 17\)

#### Part II: Number Lines
A. \(1 + 8 = 9\)
B. \(2 + 8 = 10\)
C. \(3 + 8 = 11\)
D. \(4 + 8 = 12\)
E. \(7 + 8 = 15\)
