Teacher's field guide

What Students Need to Do: Students identify what each side gives up and gets in a trade. They explain why both expect to be better off and how trade can give people more choices.
What Mastery Looks Like: Given a baker trading bread for herbs, a student explains why the baker wants herbs and the gardener wants bread. They note that either side can refuse and that their gains need not be equal. They connect exchanges like this to more choices for buyers and sellers.
Common Misconceptions: Some students think every trade has a winner and a loser, or that both sides must gain the same amount. Others think agreeing to a trade guarantees a good outcome, rather than showing what each person expects at the time.
How to Assess It: Exit ticket: A baker trades a loaf of bread for a gardener's herbs. Why might each agree, and how could trades like this give neighbors more choices?
