ACTIVITY
| Circle
Graphs: |
Estimate the relative
size of regions of a circle as a percent. Use the given data to calculate
percents and draw circle graphs. |

| Optional: |
Transparent circle protractor If
possible, use a transparent circle protractor and consider the relationship
between degree measure and percent. These activities require you to estimate
percent regions. For example, you should realize that 25% is 1/4 of a circle,
which is 90 degrees. Other reference percents to consider include: 10% (36
degrees), 50% (180 degrees), and 75% (270 degrees).
The Circle Graph
activity could be expanded to include estimating the number of degrees in each
region divided by the whole quantity (base). |
Pie Chart Meter
Using the circle below; shade in each of the following
percentages: 90%, 100%, 83.3%, 75% and 66.6%.
