What This Standard Means
What Students Need to Do
- Students locate the Mississippi River and the 31st parallel on a map. They explain that the 1783 treaty set the river as a western boundary and claimed the 31st parallel as a southern boundary. A later treaty with Spain confirmed that southern line.
What Mastery Looks Like
- A student can mark both boundaries and find where present-day Alabama sits on the map. They can explain that land north of the 31st parallel fell within the U.S. claim, while Mobile remained in Spanish territory.
Common Misconceptions
- Students may think all of present-day Alabama became U.S. land in 1783. They may also confuse the Mississippi River with the state of Mississippi, or assume the later treaty moved the boundary instead of settling a dispute over it.
How to Assess It
- Give students a map showing the Mississippi River, the 31st parallel, Mobile, and Alabama’s current outline. Ask them to label the two treaty boundaries and write one sentence explaining why Mobile was not yet U.S. territory.

Ways to Teach It
Give pairs a blank regional map and colored pencils to trace the Mississippi River, the 31st parallel, and Alabama’s current outline.
Ask students to write two sentences answering, “Why did the United States and Spain need another treaty after 1783?”
Play a map-card sort: students place cards labeled Mississippi River, 31st parallel, and Mobile under U.S. boundary or Spanish territory.
Show a current Alabama road map and have students find Mobile, then compare its location with the 31st parallel on a historical map.
