Teacher's field guide

What Students Need to Do: Students trace how goods and money move between countries. They explain how a change in one country affects buyers and competing sellers elsewhere.
What Mastery Looks Like: A student can name the buyer, seller, and competing seller in a trade example. They can explain why a supply shortage may raise prices for buyers and bring more sales to another exporter.
Common Misconceptions: Students may think imports only hurt workers or that every country gains equally from trade. They may miss how a shortage abroad can change local prices and sales for competing exporters.
How to Assess It: Exit ticket: Vietnam's coffee harvest falls. What might happen to a U.S. coffee shop and a Brazilian coffee grower, and why?

Lesson moves

Give groups yarn and coffee supplier cards for Vietnam and Brazil; connect suppliers to a U.S. roaster, then reroute after a Vietnamese drought.
Ask: If U.S. shops switch from Vietnamese to Brazilian coffee, who gains, who loses, and what might happen to prices?
Run a supplier-bid game: give shop teams cost and shipping cards for three countries, then announce a drought and let teams rebid.
Bring two single-origin coffee bags to class; students find each source country and compare shelf prices, then suggest reasons for the difference.
