Summit, MO Adapted from Math Thematics, Book 1
2
In this lesson you will...

• Learn how to draw
• and interpret a line plot.

3
Materials you will need...

• Pencil
• Paper

4
Work as a Team...

• 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!

5
Lets Begin!
6
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.
7
show the lengths of five giant invertebrates.
This table
and line plot
8
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?
9
How do you think the data in the table was used
to draw the line plot?
What information is lost when you transfer data
from a table to a line plot?
10
What is the longest length of the giant
invertebrates shown?
The shortest length?
What is the range of the data?
11
Which is easier to use, the table or the line
plot, to find the longest and the shortest
lengths?
Why?
12
What numbers start and end 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.

14
Now you try it!

• Use the table on the next slide to construct a
  line plot.

15
Make Your Own Line Plot
16
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.)
17
How many hours a day do you think a zebra sleeps?
18
How many hours a day do you think a beaver
sleeps?
19
On a new sheet of paper...

• List 3 things you liked or disliked about math
  today.
• 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.
