# Line plots review

CCSS Math: 3.MD.B.4
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 $17$ turtles traveled in an hour (we know it is $17$ turtles because there are $17$ dots on the line plot).
The $3$ dots above $21$ mean that $3$ turtles traveled a distance of $21$ 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 $4,5,5, 6$ would look like this:

## Practice set 2: Graphing data on line plots

Problem 2A
$5$ friends made new necklaces.
The lengths were $52$, $51$, $52$, $54$, and $52$ centimeters.

Make a line plot of the lengths.
