What This Standard Means
What Students Need to Do
- Students compare a legal maximum or minimum price with the price where buyers and sellers agree. They predict whether there will be too many buyers or too many goods, then explain how people respond.
What Mastery Looks Like
- If a market clears at $10, a student can explain why a $7 price cap leaves some buyers without goods and a $13 minimum leaves goods unsold. They can name likely responses, such as waiting in line or selling less.
Common Misconceptions
- Students may think any price cap causes a shortage, even if it is above the market price. They may call unsold goods a shortage or assume sellers can raise a price that the law caps.
How to Assess It
- Exit ticket: A market clears at $10. For a $7 cap and a $13 minimum, give the legal price, identify the shortage or surplus, and name one buyer or seller response.

Ways to Teach It
Run a snack market with buyer and seller cards, find the clearing price, then set a lower price cap and count unmet buyers.
Ask, 'If a town caps apartment rents below the market price, who gets an apartment, who keeps searching, and why?'
Give pairs price-rule and outcome cards for a $10 market; race to match a $7 cap and $13 minimum to their effects.
Show a rent-control notice from a city housing website, then ask students how the cap might change apartment searches and listings.
