Activator:Smarties
Open your roll of Smarties and sort them in the matching color column on your paper (one in each block)
![Page 5: Representing Data with Charts and Graphs](https://reader036.fdocuments.net/reader036/viewer/2022062309/56813af4550346895da372bd/html5/thumbnails/5.jpg)
Activator:Smarties
Now, color in the cells (rectangles) that matched the number of Smarties in each color. Complete the bottom part of your sheet.You can then eat your Smarties

Tomorrow you will be creating your own graph based on a survey you will conduct of your classmate. Tonight, you need to decide on what your topic will be.
Choices:• Favorite ice cream (choose 3 flavors plus OTHER)• Favorite subject (math, science, language arts, soc. studies)
• Favorite color (choose from 3 colors plus OTHER)• Favorite soda (choose from 3 plus OTHER)• Favorite holiday (choose from Christmas,
Halloween, Thanksgiving, and OTHER)

Bar Graph
Double Bar Graph
Bar graphs use bars of differentlengths to show andcompare numerical data.Double bar graphs use more than one bar to be able to compare more than one set of data on the same graph.

You will use the rest of the class to ask your classmates their preference (choice) for the survey that you have selected. Keep track of the responses using tally marks. For homework, you will then create a bar graph on the graph paper showing your results.
Choices:• Favorite ice cream (choose 3 flavors plus OTHER)• Favorite subject (math, science, language arts, soc. studies)
• Favorite color (choose from 3 colors plus OTHER)• Favorite soda (choose from 3 plus OTHER)• Favorite holiday (choose from Christmas,
Halloween, Thanksgiving, and OTHER)

Circle Graph
(Pie Chart)
Circle Graphs (pie charts) are used to compare parts of a group to the whole group. The whole circle is the whole group.

Pictographs
also called picture graphs
Pictographs use pictures or symbols to represent data amounts.

PictographsPay attention to the key when using pictographs because the picture or symbol may represent more than one like in the example below:

Line Graph
Line graphs are used to show how data changes over time.Double line graphs use more than one line to be able to compare more than one set of data.

New York City, recorded for 6 days, in degrees Fahrenheit.
Temperatures In NY City
Day Temperature
1 43° F
2 53° F
