## HMH Into Math Grade 4 Module 19 Lesson 5 Answer Key Represent and Interpret Measurement Data in Line Plots

I Can make a line plot and use a line plot to answer questions.

Connect to Vocabulary
A line plot is a graph that records each piece of data on a number line.

Step It Out

Question 1.
The weights of some cellphones and tablets are shown. How can you display the data using a line plot? A. Order the data from least to greatest.
The weights of some cellphones and tablets data are given in pounds.
The given data are 3/4, 1 3/8, 1 1/2, 3/8, 1/4, 1/4.
The mixed fraction 1 3/8 in fraction form as 11/8.
The mixed fraction 1 1/2 in fraction form as 3/2.
The given data from least to greatest are 1/4, 1/4, 3/8, 3/4, 1 3/8, 1 1/2.

B. Complete the tally table.  C. To determine the intervals, look at the fractions and determine which common denominator you could use. Which interval would you use to make the number line?
We can use common denominator as 8. The interval used to make the number line is 1/8.

D. Label the fraction lengths on the number line. Plot an X for each data point. Write a title, and label the units used.  Question 2.
The line plot shows the widths of different portable music players. How much greater is the width of the widest portable music player than the narrowest? A. Draw a box around the value that shows the width of the narrowest portable music player. Draw a circle around the value for the widest. B. Determine which operation to use to find the answer. Write an equation and solve.
The operation I used to find the answer is subtraction.
The mixed fraction of 1 1/8 is 9/8.
The equation is 1 1/8 – 1/4
9/8 – 1/4 = 7/8

C. The widest portable music player is inches wider than the narrowest.
The widest portable music is 9/8.
The narrowest portable music is 1/4.
9/8 – 1/4 = 7/8
The widest portable music player is 7/8 inches wider than the narrowest.

Turn and Talk How does knowing equivalent fractions help you make a line plot?

Question 1.
The thicknesses of different e-readers are shown.
$$\frac{3}{8}$$ in., $$\frac{3}{4}$$ in., $$\frac{3}{8}$$ in., $$\frac{3}{8}$$ in., $$\frac{3}{8}$$ in., $$\frac{1}{4}$$ in.,
Show the data on a line plot. Question 2.
Suppose all the e-readers were stacked on top of each other. What would the thickness of the stack of e-readers be? The thicknesses of different e-readers are in inches 3/8, 3/4, 3/8, 3/8, 3/8, 1/4.
The e-readers were stacked on top of each other.
3/8 + 3/4 + 3/8 + 3/8 + 3/8 + 1/4 = 20/8 inches
The thickness of the stack of e-readers be 20/8 or 5/2 inches.

Question 3.
Model with Mathematics Erik measures how much six plants grow in two weeks. Make a line plot to display the data. Include a title and label the units.  Question 4.
The data show the different weights of some AA and AAA batteries. Complete the tally table, and make a line plot to represent the data. $$\frac{3}{8}$$ oz, $$\frac{5}{8}$$ oz, $$\frac{7}{8}$$ oz, $$\frac{5}{8}$$ oz, $$\frac{3}{8}$$ oz, $$\frac{5}{8}$$ oz   Question 5.
The line plot shows the distances Sara walks at different times of the day according to her pedometer. How far does Sara walk during the day?
1/8 + 1/8 + 2/8 + 5/8 + 8/8 = 17/8 miles
Sara walk 17/8 miles during the day.

Question 6.
Attend to Precision Use the tally table to make a line plot to represent the data.  Question 7.
Use Tools A wildlife center records the weights of six reptiles. The fractions represent the weights, in pounds, of the reptiles. Make a line plot to display the data. What is the difference in weight between the heaviest and lightest reptiles weighed?
$$\frac{5}{8}$$, $$\frac{9}{8}$$, $$\frac{5}{8}$$, $$\frac{7}{8}$$, $$\frac{7}{8}$$, $$\frac{8}{8}$$
