What This Standard Means
What Students Need to Do
- Students explain how buyers and sellers choose what serves their goals. They predict how rewards and costs can change those choices.
What Mastery Looks Like
- Given a price change or fee, a student can predict how a buyer or seller might respond and explain why. They can also explain why two people might make different choices.
Common Misconceptions
- Students may think incentives are only cash rewards, missing fees, time saved, or convenience. They may treat self-interest as greed or assume every shopper responds to a coupon the same way.
How to Assess It
- Exit ticket: A cafe offers 50 cents off for reusable cups and charges 25 cents for disposable cups. Predict one customer's choice and explain how the discount and fee affect it.
