1. 25% + 25% + ____ = 100%

2. 50% + 25% + ____ = 100%

3. 15% + 10% + ____ = 100%

4. 35% + 10% + ____ = 100%

Circle Graph: a graph of data where the entire circle represents the whole.

 

 

20 minutes

Explore (Conceptual Development)

Tell students that the best way for them to understand circle graphs is by creating them. Split students into pairs, and give each pair a paper plate and a small bag of M&Ms. Draw an example of the finished product on the board as you take students through each step.

1)       Group colors

2)       Line around perimeter

3)       Draw a dot in the center of the plate

4)       Using a ruler, draw a straight line from the edge of a color section to the dot, so M&Ms of the same color are in a wedge together with all lines meeting in the middle.

5)       Color each section to match the M&M color.

6)       Remove M&Ms and view circle graph!

Get into pairs. Follow steps 1-6 as demonstrated. Both members of the pair are expected to be actively participating in the activity.

Explain

(Guided Practice)

Ask each pair to share their circle graph. Create a class data table that will allow each group to record how many of each color M&M they had. Once each pair has shared, use the data to calculate the mean for each color.

Share circle graph with class. Record data in the data table and actively work to calculate the class mean for each color.

15 minutes

 

Extend/ Elaborate

 

Pass out a worksheet that requires students to interpret circle graphs based on the data provided. Circulate the room and provide assistance, or pull aside a small group if necessary.

Complete the graphing worksheet independently.
