### Eureka Math Grade 5 Module 4 Lesson 1 Problem Set Answer Key

Question 1.
Estimate the length of your pencil to the nearest inch. ______________
6 inch

Explanation:
The length of the pencil to the nearest inch is 6.

Question 2.
Using a ruler, measure your pencil strip to the nearest $$\frac{1}{2}$$ inch, and mark the measurement with an X above the ruler below. Construct a line plot of your classmates’ pencil measurements.

Explanation:
By using a ruler, I have measured the pencil strip to the nearest inch and marked the measurement with an X above the ruler.

Question 3.
Using a ruler, measure your pencil strip to the nearest $$\frac{1}{4}$$ inch, and mark the measurement with an X above the ruler below. Construct a line plot of your classmates’ pencil measurements.

Explanation:
By using a ruler, I have measured the pencil strip to the nearest inch and marked the measurement with an X above the ruler.

Question 4.
Using a ruler, measure your pencil strip to the nearest $$\frac{1}{8}$$ inch, and mark the measurement with an X above the ruler below. Construct a line plot of your classmates’ pencil measurements.

Explanation:
By using a ruler, I have measured the pencil strip to the nearest inch and marked the measurement with an X above the ruler.

Question 5.
Use all three of your line plots to complete the following:
a. Compare the three plots, and write one sentence that describes how the plots are alike and one sentence that describes how they are different.
All the 3 line plots are similar because they all show that the majority of the pencil lengths were between 4 and 5 1/2 inches. The 3rd line plot looks different from the others because there’s usually only 1 pencil per measurement, except for 4 5/8 and 4 3/4 in.

b. What is the difference between the measurements of the longest and shortest pencils on each of the three-line plots?
Line Plot 1: 7 in – 2 1/2 in = 4 1/2 in.
Line Plot 2: 7 in – 2 1/4 in = 4 3/4 in.
Line Plot 3: 7 in – 2 3/8 in = 4  5/8 in.

Explanation:
The difference between the measurements of the longest and shortest pencils on each of the three-line plots are
Line Plot 1: 7 in – 2 1/2 in = 4 1/2 in, Line Plot 2: 7 in – 2 1/4 in = 4 3/4 in, Line Plot 3: 7 in – 2 3/8 in = 4  5/8 in.

c. Write a sentence describing how you could create a more precise ruler to measure your pencil strip.
The most precise ruler we’ve used so far had us measure to the nearest 1/8 inch. We could divide each 1/8 into 2 equal parts as a measure to the nearest 1/16 inch.

Explanation:
I have written a sentence describing how we could create a more precise ruler for measuring the pencil strip.
