NUMBEROCK Fractions on a Line Plot Song:
Mini-Lesson
Mini-Lesson
Yesterday, we learned to measure the length of items using customary measurement.
Today, we will learn how to take data and place it on a line plot or a dot plot to organize it. Listen as I think aloud about this next problem:
Kade measured the hand lengths of her class to the nearest eighth inch.
How can Kade display the hand lengths in a line plot?
We will use the class’s hand length measurement to create a line plot to display the data. A line plot is a tool used to display measurement data. Let’s first look at this table and see what it shows us. The hand measurements are listed on the top row, and the unit of measurement is inches. The bottom row labeled “count” tells us the number of students whose hands measured that length. For example, there are 3 students whose hands measured 5 6/8 inches.
To create a line plot, I first need to determine the endpoints of my number line. The smallest measurement is 5 inches, and the largest measurement is 6 inches. I will draw a horizontal line and place 5 and 6 on the endpoints.
Watch as I partition it into eight equal parts and label each fraction while I think aloud. Be sure to title the line plots with a title that tells what the data represents, and the units of measure should also be labeled on the line plot.
Notice how I plot the X’s on the line plot for each data point. For example, I see three students' hands measured 5 6/8 inches, so I will place three Xs above 5 6/8.
Completed line plot:
Now that we have completed our line plot, we can use the data displayed to answer some questions about our class hand measurements.
What is the difference between the longest and shortest hand length?
I see the shortest hand is 5 1/8 inches, and the longest is 6 inches. I can subtract to find the difference.

Now, I would like you to interpret the data on the line plot and draw some conclusions based on it.
Click the dropdown for some possible answers:
The most common hand length was 5 4/8 inches.
No one had hand lengths of 5 inches or 5 3/8 inches.
All hand lengths were longer than 5 inches.
