What This Standard Means

What Students Need to Do

Students locate major sources of a resource on maps from two dates and compare where extraction rises or falls. They trace trade routes and explain effects on producing and buying communities.

What Mastery Looks Like

Given copper production maps for 2000 and 2020, a student identifies a change in output without claiming the ore deposits moved. They explain why a country buys copper and name one effect on a mining town, such as jobs or water use.

Common Misconceptions

Students may read a larger production symbol as a new deposit, when it can mean more mining. They may assume every country with copper mines exports copper or that buyers always choose the nearest supplier.

How to Assess It

Give students copper production maps for 2000 and 2020, plus an arrow from Chile to China. Ask them to name one production change, explain why China buys copper, and describe one effect on a Chilean mining town.

Lesson moves

Ways to Teach It

  1. Give pairs two dated copper production maps, sticky dots, and yarn; have them mark major sources and string a route from Chile to China.

  2. Ask students to write: If copper output falls in one region, what might change for its miners and buyers?

  3. Give teams Chile and Peru source cards and a China buyer card; award points for correct placement and plausible copper routes.

  4. Bring a coffee bag with its origin listed; students map that country and draw a route to their local grocery store.
