# Problem Solving: Mapmaker, Mapmaker

### Product Description:

On a political map, regions that share borders often have different colors. Mathematicians have proved that no map needs more than four colors!

## Teaching Tip:

Taking It Further Challenge students to create three of their own maps—one that needs two colors, one that needs three, and one that needs four. Compile the uncolored maps in a folder. Invite students to color the maps as indicated. This activity corresponds to the following NCTM standards: • Geometry • Problem Solving
