The task involves measuring the length of various objects using a ruler and recording the measurements to the nearest 1/4 inch. Below is a step-by-step explanation of how to solve this problem:
---
Step 1: Understand the Ruler
- The ruler in the image is marked in inches.
- Each inch is divided into smaller segments:
- The
largest lines represent whole inches (e.g., 1, 2, 3).
- The
second-largest lines represent half-inch marks (e.g., 0.5, 1.5, 2.5).
- The
third-largest lines represent quarter-inch marks (e.g., 0.25, 0.75, 1.25, etc.).
- The
smallest lines represent eighth-inch marks.
For this worksheet, we are asked to measure to the nearest
1/4 inch. This means we will focus on the quarter-inch marks.

Step 2: Measure Each Object
We need to measure the length of each object shown in the worksheet. Let’s go through them one by one:
####
Object 1: Pencil
1. Align the left end of the pencil with the 0-inch mark on the ruler.
2. Observe where the right end of the pencil falls on the ruler.
3. The right end of the pencil appears to be between the 6-inch and 7-inch marks.
4. It is closer to the 6.5-inch mark (half-inch) than to the 6.25-inch or 6.75-inch marks.
5. Therefore, the measurement is
6.5 inches.
####
Object 2: Eraser
1. Align the left end of the eraser with the 0-inch mark on the ruler.
2. Observe where the right end of the eraser falls on the ruler.
3. The right end of the eraser appears to be between the 1-inch and 2-inch marks.
4. It is closer to the 1.25-inch mark (quarter-inch) than to the 1-inch or 1.5-inch marks.
5. Therefore, the measurement is
1.25 inches.
####
Object 3: Highlighter
1. Align the left end of the highlighter with the 0-inch mark on the ruler.
2. Observe where the right end of the highlighter falls on the ruler.
3. The right end of the highlighter appears to be between the 2-inch and 3-inch marks.
4. It is closer to the 2.75-inch mark (three-quarter-inch) than to the 2.5-inch or 3-inch marks.
5. Therefore, the measurement is
2.75 inches.
####
Object 4: Pen
1. Align the left end of the pen with the 0-inch mark on the ruler.
2. Observe where the right end of the pen falls on the ruler.
3. The right end of the pen appears to be between the 5-inch and 6-inch marks.
4. It is closer to the 5.5-inch mark (half-inch) than to the 5.25-inch or 5.75-inch marks.
5. Therefore, the measurement is
5.5 inches.

Step 3: Record the Measurements
Now, record the measurements for each object in the provided spaces on the worksheet:
1. Pencil:
6.5 inches
2. Eraser:
1.25 inches
3. Highlighter:
2.75 inches
4. Pen:
5.5 inches

Final Answer
\[
\boxed{6.5, 1.25, 2.75, 5.5}
\]

Explanation
- Always align the object with the 0-inch mark on the ruler for accurate measurements.
- Focus on the quarter-inch marks when determining the nearest 1/4 inch.
- Estimate carefully if the object falls between two marks, choosing the closest one.
This method ensures precise and consistent measurements.
