To help Grade 9 students understand how and why countries trade. Students are divided into teams, each of which acts as a separate ‘country’, with between two and ten students in each team. There are five or six countries in a game. A game thus can be played with between 10 and 60 students. More than one game can be played simultaneously, if the room is big enough, but there must be no interaction between the games.
Countries compete against each other to ‘manufacture’ paper shapes (circles, triangles, rectangles, etc.) and sell them to an international commodity market trader at posted prices, which vary with supply and demand. The objective for each country is to make as much money as possible.
