Eureka Math Grade 5 Module 4 Lesson 1 Problem Set Answer Key
Question 1.
Estimate the length of your pencil to the nearest inch. ______________
Answer:
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.
Answer:
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.
Answer:
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.
Answer:
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.
Answer:
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?
Answer:
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.
Answer:
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.

Eureka Math Grade 5 Module 4 Lesson 1 Homework Answer Key
A meteorologist set up rain gauges at various locations around a city and recorded the rainfall amounts in the table below. Use the data in the table to create a line plot using \(\frac{1}{8}\) inches.
|
Location |
Rainfall Amount (inches) |
| 1 | \(\frac{1}{8}\) |
| 2 | \(\frac{3}{8}\) |
| 3 | \(\frac{3}{4}\) |
| 4 | \(\frac{3}{4}\) |
| 5 | \(\frac{1}{4}\) |
| 6 | 1\(\frac{1}{4}\) |
| 7 | \(\frac{1}{8}\) |
| 8 | \(\frac{1}{4}\) |
| 9 | 1 |
| 10 | \(\frac{1}{8}\) |
a. Which location received the most rainfall?
Answer:
Location 6
Explanation:
Location 6 has received the most rainfall.
b. Which location received the least rainfall?
Answer:
Location 1, 7, 10
Explanation:
Location 1,7,10 has received the least rainfall.
c. Which rainfall measurement was the most frequent?
Answer:
1/8 inch
Explanation:
The most frequent rainfall measurement was 1/8 inch.
d. What is the total rainfall in inches?
Answer:
5 Inches.
Explanation:
5 inches is the total rainfall and I have given the explanation below.
1/8 + 3/8 + 3/4 + 3/4 + 1/4 + 1 1/4 + 1/8 + 1/4 + 1 + 1/8
4/8 + 6/4 + 1 2/4 + 1/4 + 1 2/8
1 6/8 + 1 9/4
2 3/4 + 9/4
2 12/4
5 inches.
