Lesson 1 EQ: How do I represent data using bar graphs (and double bar graphs)? SPI

4
Activator: Smarties Open your roll of Smarties and sort them in the matching color column on your paper (one in each block)

5
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

Number 1s pick three vocabulary words to define for your partner. Number 2s then pick three different words to define for your partner. Vocabulary Words: datatitleaxissurvey rowcolumncelllegend (key) tallyinterval (scale) Numbered Heads (Think Pair Share )

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) Homework

10
On your index card, write three of the vocabulary words below followed by the definition. Make sure your name is on your card. Vocabulary Words: datatitleaxissurvey rowcolumncelllegend (key) tallyinterval (scale) Ticket Out the Door

Look at the Types of Graphs foldable

13
Bar Graph Double Bar Graph Bar graphs use bars of different lengths to show and compare 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) Classwork / Homework

On your index card, write the answer to the EQ: How do I represent data using bar graphs (and double bar graphs)? Make sure your name is on your card. Ticket Out the Door

Lesson 2 EQ: How do I represent data using circle graphs and pictographs? SPI

22
Activator: Sporty Selections Pass to exactly 12 classmates

23
Look at the Types of Graphs foldable

24
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.

26
More examples of circle graphs

27
Pictographs also called picture graphs Pictographs use pictures or symbols to represent data amounts.

28
Pictographs Pay attention to the key when using pictographs because the picture or symbol may represent more than one like in the example below:

Lesson 3 EQ: How do I represent data using line graphs (and double line graphs)? SPI

36
Activator: BrainPop - Graphs

37
Look at the Types of Graphs foldable

38
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.

39
Line Graph example Example 1:The table below shows daily temperatures for New York City, recorded for 6 days, in degrees Fahrenheit. Temperatures In NY City DayTemperature 143° F 253° F 350° F 457° F 559° F 667° F The data from the table above has been summarized in the line graph to the right.
