Line PlotsSusan Phillips
Meadow Lane ElementaryLee’s Summit, MO
Adapted from Math Thematics, Book 1
In this lesson you will...
Learn how to draw
and interpret a line plot.
Materials you will need...
PencilPaper
Discuss each slide.
Do not go on until you are sure everyone on the team understands the concept presented on the slide.
Take your time.
Have fun!
Work as a Team...
Let’s Begin!
In this lesson, we will work with animal data.
The first type of animals we will use are invertebrates.
Invertebrates are animals without backbones. They are often very small.
However, we will be investigating
very LARGE invertebrates.

show the lengths of five giant
invertebrates.
Suppose you pick up a bird-eating spider.
Will it fiton the tip of your finger,
in the palm of your hand, or in both hands?

the line plot?

Why do you think these numbers were
chosen?
Line Plots A line plot displays data using a line marked with a
scale. The scale must include the greatest and least value
of the data. If you make a line plot before having all your data,
you may want to include some extra numbers to the left and right in case the data includes some surprisingly small or large data.
Now you try it! Use the table on the next slide to
construct a line plot.

Use the table and your line plot to help you estimate how many hours
a day each of the following animals sleep.
(Hint: Look at the clusters of animals in your line plot. Think about what each animal eats and where it sleeps.)
How many hours a day do you think a zebra sleeps?

List 2 ways line plots are different than bar graphs.
List 1 thing you learned today that you did not expect to learn in math class.
Zippidy Do Dah!!!!
You are ready to practice making line plots.
