World communities have needs, wants, and limited resources. To meet their needs and wants, communities trade with others. Technological developments in transportation and communication have influenced trade.

Key Idea 3.10

What This Standard Means
What Students Need to Do
- Students identify what selected communities sell to others and what they buy from others. They explain why limited local resources lead to trade, then use simple supply and demand examples to predict price changes. They compare how ships, airplanes, phones, and the internet changed trade.
What Mastery Looks Like
- Given a community profile, a student correctly labels products and services as imports or exports and explains the trade using available resources. The student predicts that scarce, highly wanted goods tend to cost more and names one technology that made trade faster or wider.
Common Misconceptions
- Students often reverse import and export, especially when the same product moves between several places. They may think trade includes only goods, that communities can produce everything they need, or that high demand always lowers prices. They may overlook communication tools and focus only on trucks, ships, and planes.
How to Assess It
- Exit ticket: A mountain community grows coffee but has no computer factories, and many families suddenly want computers. Name one export, one import, predict what may happen to computer prices, and explain how one technology could support the trade.

Ways to Teach It
Place coffee, computer, tourism, and shipping cards on import or export mats for two sample communities, then justify each placement.
Discuss or write: Why would an island community trade fish for medicine, and how could a phone help arrange the exchange?
Run a token market where item supplies change each round, and students record how scarcity and buyer demand affect prices.
Check labels on classroom objects, map their origins, and choose the transportation and communication tools likely used to bring them nearby.
