01

What Students Need to Do

Students map how Texas joined the United States and how the Mexican Cession and Gadsden Purchase followed. They compare why gold seekers, Oregon settlers, and Mormon migrants moved west. They trace the effects on Mexican families, Native nations, and debates over slavery.

02

What Mastery Looks Like

A student can put Texas annexation, the war with Mexico, the peace treaty, and the Gadsden Purchase in order and explain how each changed the map. They can explain why treaty promises of citizenship did not keep some Mexican families from losing land. They can describe a Native nation's loss of homeland or control and explain why new territories raised arguments over free and slave states.

03

Common Misconceptions

Students may think Texas, the Mexican Cession, and the Gadsden Purchase were all bought in one deal. They may assume a promise of citizenship protected Mexican families' land. Some picture the West as empty or think gold seekers, Oregon settlers, and Mormon migrants all moved for the same reason.

04

How to Assess It

Give students a map labeled Texas, the Mexican Cession, and the Gadsden Purchase. Ask them to number the additions in order, then name one effect on Mexican landowners or a Native nation and one reason lawmakers argued over slavery.

1. 01

   Give pairs an 1840s map and dated event cards to shade Texas, the Mexican Cession, and the Gadsden Purchase.

2. 02

   Give students a treaty excerpt and a land claim account; ask how citizenship and land loss could happen together.

3. 03

   Run a card sort matching gold miners, Oregon settlers, and Mormon migrants to distinct goals and effects on Native homelands.

4. 04

   Open the Navajo Nation government website beside an 1848 cession map; ask how a changed border affected Navajo self-government.
