Review the basics of lines plots and then practice creating and reading line plots.

What are line plots?

A line plot is a way to display data along a number line.
Line plots are also called dot plots.
Below is an example of a line plot showing the distance 1717 turtles traveled in an hour (we know it is 1717 turtles because there are 1717 dots on the line plot).
The 33 dots above 2121 mean that 33 turtles traveled a distance of 2121 meters in an hour.

Graphing data on line plots

To graph data on a line plot, we put a dot (or an X) above each number in the data set. If a number appears twice in the data, we put two dots above that number.
For example, a graph of the data set 4,5,5,64,5,5, 6 would look like this:

Practice set 2: Graphing data on line plots

Problem 2A
55 friends made new necklaces.
The lengths were 5252, 5151, 5252, 5454, and 5252 centimeters.

Make a line plot of the lengths.
