The multimedia library on The Economist contains a set of cartoon videos explaining some big concepts in economics. Of the six cartoon the cartoon on international trade has the broadest appeal. The video is appropriate as an introduction to the topic for middle school and high school students.
After watching the video on international trade have your students put their new knowledge to use in Trading Around the World from the International Monetary Fund. The object of the game is to provide students with knowledge of the variables affecting international trade. Students experience the impact of each variable by playing the game as a representative of a country or region that is trying to buy or sell resources. The overall object of the game is to accumulate cash through buying and selling natural resources.
