What This Standard Means
What Students Need to Do
- Students turn trade data from two years into maps, tables, or timelines showing where goods and services move. They compare routes and amounts to explain which countries rely on each other and which have few recorded links.
What Mastery Looks Like
- A student labels trade arrows with the origin, destination, year, and good or service. They use trade amounts to explain a growing connection without treating a missing arrow as proof that no trade exists.
Common Misconceptions
- Students may draw arrows backward or treat software services as physical shipments. They may assume a blank route means no trade, or mistake a large one-way flow for balanced exchange.
How to Assess It
- Exit ticket: Use these sample flows, in $ billions: Mexico to US vehicles, 2005: 30 and 2020: 90; US to Mexico machinery, 2005: 20 and 2020: 50; Kenya to US tea, 2005: 1 and 2020: 2. Draw arrows for both years, then name one growing two-way link and one weaker recorded link.

Ways to Teach It
Give pairs trade cards for chips, phones, and software in 2005 and 2020; have them draw labeled arrows on two blank world maps.
Ask: Does a missing arrow on our trade map prove two countries never trade, or could our cards leave out a link?
Play trade-route match: students pair six good and service cards with exporter, importer, and year cards, then check their arrows against a map key.
Check labels on three classroom items, mark their listed production countries on a map, and discuss what the labels cannot show about services.
