Students use this worksheet to measure pairs of objects like arrows, fish, and birds, then calculate the difference in their lengths.

Since the image is a worksheet titled "Comparing Two Measurements", and you've asked me to solve the problem, I’ll walk through how to approach it step by step. However, since this is a visual task involving measurement with non-standard units (like paper clips, blocks, or other objects), and no actual ruler or physical object is provided, we need to simulate the process assuming that the student would use a consistent unit (e.g., a small block or a paperclip) to measure each object.

Let’s assume the student uses a standard unit of length (such as "paperclips" or "blocks") to measure the lengths of the objects. We'll estimate based on typical proportions in such worksheets.

Step-by-Step Solution:

We are told to:
1. Measure each object using one common unit.
2. Compare the two measurements.

Let's go section by section.

#### Section 1: Arrows A and B

- Arrow A: appears shorter
- Arrow B: longer

Assume we use "units" like paperclips.

Let’s say:
- Arrow A = 3 units
- Arrow B = 5 units

Then:
> Arrow A is 2 units shorter than Arrow B.

✔ Fill in:
- Arrow A: (length) 3, (units) paperclips (or whatever unit chosen)
- Arrow B: (length) 5, (units) paperclips
- 1. Arrow A is 2 units shorter than Arrow B.

#### Section 2: Fish C and D

- Fish C is much longer than Fish D.
- Assume:
- Fish C = 6 units
- Fish D = 3 units

Then:
> Fish C is 3 units longer than Fish D.

✔ Fill in:
- Fish C: (length) 6, (units) paperclips
- Fish D: (length) 3, (units) paperclips
- 2. Fish C is 3 units longer than Fish D.

#### Section 3: Birds E and F

- Bird E is smaller than Bird F.
- Assume:
- Bird E = 4 units
- Bird F = 6 units

Then:
> Bird E is 2 units shorter than Bird F.

✔ Fill in:
- Bird E: (length) 4, (units) paperclips
- Bird F: (length) 6, (units) paperclips
- 3. Bird E is 2 units shorter than Bird F.

Final Answer Summary:

| Object | Length (units) | Unit |
|-------|----------------|------|
| Arrow A | 3 | paperclips |
| Arrow B | 5 | paperclips |
| Fish C | 6 | paperclips |
| Fish D | 3 | paperclips |
| Bird E | 4 | paperclips |
| Bird F | 6 | paperclips |

Answers:
1. Arrow A is 2 units shorter than Arrow B.
2. Fish C is 3 units longer than Fish D.
3. Bird E is 2 units shorter than Bird F.

Important Notes:

- The actual numbers may vary slightly depending on the size of the unit used (e.g., if using a different-sized block or paperclip).
- The key concept is consistency: using the same unit for both objects in each pair.
- This activity helps students understand relative size, measurement, and comparison using non-standard units.

If you have a physical copy of this worksheet and want to use real measurements, please use a ruler or a consistent object (like a pencil eraser) to measure from tip to tip of each item and fill in accordingly.
