Give each kid a paper lunch bag with a surprise inside! The item in their bag should be a natural resource or product that is abundant in their country. Kids trade the item in their bag to obtain a good that their country wants or needs. They begin trading "locally," with each other. Then, they trade items "world wide," with all of their classmates. In the end, each team should have 2 items their country needs and 2 items their country wants.
