Lesson Time: 50 minutes
In this very active lesson, students represent goods being traded among countries. As the students move in trade, they encounter physical barriers (long-jump, hurdle, and limbo bar) that represent natural and government-imposed trade barriers. Through the activities, students see that trade barriers reduce the flow of goods and services among countries and, as a result, reduce the gains from trade. Because of the activities in this lesson, it might be good to work with the physical education teacher.
