Line Plots

Susan Phillips Meadow Lane Elementary Lees

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...

- Pencil
- Paper

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!

Lets 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.

This table

and line plot

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?

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?

What is the longest length of the giant

invertebrates shown?

The shortest length?

What is the range of the data?

Which is easier to use, the table or the line

plot, to find the longest and the shortest

lengths?

Why?

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.

Now you try it!

- Use the table on the next slide to construct a

line plot.

Make Your Own 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?

How many hours a day do you think a beaver

sleeps?

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.

Zippidy Do Dah!!!!

- You are ready to practice making line plots.
