01

What Students Need to Do

Students explain how scarcity, surplus, and opportunity cost shape choices. They weigh costs, benefits, risks, and incentives when deciding what to buy or produce. They identify the resources needed to make goods and explain why people with different preferences might both gain from a trade.

02

What Mastery Looks Like

Given a school store with limited stock and money, a student can identify what is scarce or left over and name the next-best choice forgone. They can explain how a price change affects choices, which resources the store needs, and why a buyer and seller both accept a deal.

03

Common Misconceptions

Students may list every rejected option as the opportunity cost instead of the next-best choice. They may confuse surplus stock with a shortage. They may assume one person loses in every trade or that everyone values the same item equally.

04

How to Assess It

Exit ticket: A school store has 20 notebooks, and 12 students each want one at $5; you are one of them and could buy lunch for $5 instead. If all 12 buy notebooks, how many remain, what do you give up, and why might you and the store both benefit?
