01

What Students Need to Do

Students compare who decides what gets made and sold in different economic systems. They use graphs and examples from the past and present to explain how supply and demand affect prices. They explain how new businesses and inventions can give buyers more choices in their town, across the country, and around the world.

02

What Mastery Looks Like

Given a bar graph of buyers and available items, a student predicts a likely price change and uses numbers from the graph to explain it. They can explain how competing sellers give shoppers choices and how a new business might sell beyond its town.

03

Common Misconceptions

Students may think more buyers always mean higher prices, even when the number of items for sale also rises. They may confuse supply with the number of people who want an item. Some think a business owner must invent a brand-new product.

How to Assess It

Show a bar graph with 20 umbrellas for sale in both weeks, 10 buyers in week one, and 40 in week two. Ask: Which week would umbrellas likely cost more, and which numbers support your answer?
