What This Standard Means
What Students Need to Do
- Students explain why a buyer and seller each choose to make a trade. They identify market choices made by households, businesses, and governments, such as a city buying supplies.
What Mastery Looks Like
- A student can explain why a family buys bread and why a bakery agrees to sell it at that price. They can also explain why a city and a supplier might agree on a purchase, while either could reject the offer.
Common Misconceptions
- Students may think both sides must gain the same amount for a trade to be voluntary. They may call a required tax payment a voluntary exchange. Some assume governments cannot choose to buy from businesses.
How to Assess It
- Exit ticket: A city accepts a company's quote for new desks. Why might each side agree, and what could either side do before accepting?
