Barter: To trade by exchanging one commodity for another.
Looking for ways to teach kids about the economy? Why not have a trade fair! This can be done many ways. You can have students bring in "garage sale" items from home (with parents permission) or give them time to make items in class. They can create artwork or crafts to trade or bring food or items from home.
This lesson can be linked to many social studies standards. You can easily talk about supply and demand as well as needs and wants. A trade fair can also be used when studying colonial America since this was the way early Americans got their supplies.
