Measure Lengths using the ruler Worksheets for Kids Online - Free Printable

To solve this worksheet, we need to read the length of each green bar on the tape measure by finding the difference between its starting inch mark and its ending inch mark.

Each ruler shows a segment of inches (e.g., 61–65, 36–40, etc.), and the green bar spans from one inch mark to another. The length in inches is:

> Length = Ending Inch – Starting Inch

Let’s go line by line:

---

1. Top ruler: 61 to 65
- Green bar starts at 61, ends at 65
- Length = 65 – 61 = 4 inches

✔ Answer: 4

---

2. Second ruler: 36 to 40
- Green bar starts at 36, ends at 37
- Length = 37 – 36 = 1 inch

✔ Answer: 1

---

3. Third ruler: 57 to 61
- Green bar starts at 57, ends at 58
- Length = 58 – 57 = 1 inch

✔ Answer: 1

---

4. Fourth ruler: 39 to 43
- Green bar starts at 39, ends at 41
- Length = 41 – 39 = 2 inches

✔ Answer: 2

---

5. Fifth ruler: 44 to 48
- Green bar starts at 44, ends at 47
- Length = 47 – 44 = 3 inches

✔ Answer: 3

---

6. Sixth ruler: 73 to 77
- Green bar starts at 73, ends at 75
- Length = 75 – 73 = 2 inches

✔ Answer: 2

---

7. Seventh ruler: 48 to 52
- Green bar starts at 48, ends at 50
- Length = 50 – 48 = 2 inches

✔ Answer: 2

---

8. Eighth ruler: 35 to 39
- Green bar starts at 35, ends at 38
- Length = 38 – 35 = 3 inches

✔ Answer: 3

---

✔ Final Answers (from top to bottom):

4, 1, 1, 2, 3, 2, 2, 3

You can write these numbers in the blank lines next to each ruler on the worksheet.

💡 Tip for Reading Tape Measures:

Always look at where the object starts and where it ends on the ruler. Subtract the smaller number from the larger one — that’s the length!

This skill is useful in real life for measuring objects like wood, fabric, or walls!
