Students measure and compare the lengths of five pencils using a ruler in this educational worksheet.

Let’s solve this step by step.

We are given 5 pencils: A, B, C, D, and E. We need to measure each one using the ruler at the bottom (which goes from 0 to 12 inches). The left end of each pencil lines up with the 0-inch mark — so we just read where the tip ends.

Let’s measure each pencil:

- Pencil A: Starts at 0, ends at 11 → 11 inches
- Pencil B: Starts at 0, ends at 4 → 4 inches
- Pencil C: Starts at 0, ends at 10 → 10 inches
- Pencil D: Starts at 0, ends at 9 → 9 inches
- Pencil E: Starts at 0, ends at 3 → 3 inches

Now let’s answer each question:

---

1. Which pencil is the longest?
Compare all lengths:
A = 11, B = 4, C = 10, D = 9, E = 3
→ Longest is A (11 inches)

2. Which pencil is the shortest?
Shortest is E (3 inches)

3. How much longer is pencil A than pencil E?
A = 11, E = 3
11 - 3 = 8 inches

4. How much shorter is pencil B than pencil C?
B = 4, C = 10
10 - 4 = 6 inches

5. How many inches are pencil D and pencil E combined?
D = 9, E = 3
9 + 3 = 12 inches

6. Is pencil A or pencil C longer? Explain how you know.
A = 11 inches, C = 10 inches
11 > 10 → So pencil A is longer.
You can tell because when you look at the ruler, pencil A reaches farther to the right than pencil C does.

Final Answer:

1. Pencil A
2. Pencil E
3. 8 inches
4. 6 inches
5. 12 inches
6. Pencil A is longer because it measures 11 inches and pencil C measures only 10 inches. You can see on the ruler that pencil A extends further than pencil C.
