Teacher's field guide

What Students Need to Do: Students read maps to track how U.S. territory changed from the colonies to 1877. They use dates, map keys, rivers, and mountains to explain where growth happened.
What Mastery Looks Like: A student can compare maps from two periods and point out land added between them. They can use the map key to name an acquisition and locate nearby features, such as the Mississippi River or Rocky Mountains.
Common Misconceptions: Students may treat every colored area as a state, even when the key marks it as a territory. They may also assume land added to the United States was settled at the same time.
How to Assess It: Give students maps dated 1800 and 1877. Ask: "Name one area added by 1877, and identify a river or mountain range shown near it."
