With your partner, decide on some data you would like to represent on a map. Your data set should include at least 10 locations.
| location | data | area | radius |
|---|---|---|---|
- Decide on a reasonable size for the circles you will draw on your map. Make sure that the largest circle is not too large and the smallest circle is not too small. Write the scale you will use (for example, 1 million people is equivalent to 1 square centimeter). Fill in the area column so that the data will be represented by circles with area proportional to the data.
- Fill in the radius column so that a circle with that radius has the correct area.
- Write an equation that takes the data as an input and outputs the radius.
- Use a ruler and compass to draw the circles on your map.
