What This Standard Means
What Students Need to Do
- Students explain how a price change gives buyers and sellers information about demand and availability. They predict what happens when a rule holds a price below or above the price buyers and sellers would otherwise agree on.
What Mastery Looks Like
- A student can explain why a higher price may lead shoppers to buy less and sellers to offer more. Given a rent cap below the usual market price, they can predict more people seeking apartments, fewer apartments offered, and a shortage.
Common Misconceptions
- Students may think a higher price always means there is less of a good, when stronger demand can also raise prices. They may think a price cap creates more goods or that a required minimum price guarantees every seller a buyer.
How to Assess It
- Ask: A town caps apartment rents below the usual market price. What will renters and landlords likely do, and will there be a shortage or surplus?

Ways to Teach It
Give students buyer budget cards and seller cost cards, then have them trade once freely and once with a price cap; count completed trades.
Ask students to write whether a cap on bottled water prices after a storm would help buyers, and what sellers might do.
Give pairs six price-rule cards; have them sort each into likely shortage or surplus and name one buyer or seller response.
Show a sold-out concert ticket and its resale price; ask which buyers might change plans and why.
