Your Mission

You need to color the entire map of South America. This may seem simple, but but there are some rescrictions.

  1. No country may touch another country of the same color.
  2. You will be charged each time you use a color to fill in a country -regardless of its size.
  3. You must color the map as cheaply as possible.

The cost for each color is shown above.

Suggestion: First make a plan and then begin coloring.


  1. What was your plan?

  2. What is the total cost of your map?

  3. How many colors did you use?

  4. Would it be possible to use fewer colors than you did? Why or why not?
