This interactive activity can be used as a summative assessment for ratios and using proportions to determine map scales.
In pairs students go on a "Road Trip" in which they and their partner are headed toward California, making pit stops along the way. Each "pit stop" is a math problem involving ratio relationships. Students must use an actual map of the United States during the activity.
Here are some examples of questions:
Check point #1: You travel from Chicago, IL to Des Moines, Iowa. You stop and fill your gas tank.
Q1: What is the distance on the map from Chicago to Des Moines? _________________
