What This Standard Means
What Students Need to Do
- Students explain how changes in available goods and buyer interest affect prices, product availability, and consumer choices. They use examples to predict what consumers may buy or avoid.
What Mastery Looks Like
- Students can read a short market scenario and identify whether supply or demand changed. They can explain the likely effect on price and consumer behavior using evidence from the scenario.
Common Misconceptions
- Students may think high demand always means plenty of a product is available. They may also assume sellers set prices without considering shortages, surpluses, or buyer interest.
How to Assess It
- Give students this exit ticket: “A freeze destroys much of the orange crop, but shoppers still want orange juice. Predict what happens to price and explain why.”
