Westward Expansion worksheet with labeled regions of U.S. territorial growth.

The task involves labeling and coloring regions on a map of the United States based on significant events related to westward expansion. Below is the solution with explanations for each region:

Step 1: Understand the Events

The events listed are key milestones in U.S. history that led to the expansion of the country's territory. Each event corresponds to a specific region on the map. Here’s a brief overview of each:

- Location: The easternmost part of the United States, along the Atlantic coast.

2. Florida Treaty (1819)
- Spain ceded Florida to the United States.
- Location: The southeastern region, including modern-day Florida.

3. Texas Annexation (1845)
- Texas was admitted as a state after being an independent republic.
- Location: The southern central region, including modern-day Texas.

4. Treaty of Paris (1783)
- Ended the American Revolutionary War and expanded U.S. territory beyond the Appalachian Mountains.
- Location: The central and eastern regions, extending westward from the original 13 colonies.

5. Mexican Cession (1848)
- Resulted from the Mexican-American War, adding a large portion of land in the West.
- Location: The southwestern region, including parts of California, Nevada, Utah, Arizona, Colorado, and New Mexico.

10. Louisiana Purchase (1803)
- Doubled the size of the United States by acquiring land from France.
- Location: A vast central region, including parts of 15 present-day states.

Step 2: Match Events to Regions on the Map

Using the descriptions above, we can match each event to the corresponding region on the map. Here’s how the regions should be labeled:

1. Top Left Region:
- Event: Oregon Treaty (1846)
- Reason: This region includes Washington, Oregon, and Idaho, which were part of the Oregon Territory acquired through this treaty.

2. Top Middle Region:
- Event: Treaty 49th Parallel (1818)
- Reason: This region represents the northern border area affected by the treaty.

3. Top Right Region:
- Event: British Cession (1842)
- Reason: This region includes Maine and the northeastern border area affected by the treaty.

4. Middle Left Region:
- Event: Mexican Cession (1848)
- Reason: This region includes California, Nevada, Utah, and parts of Arizona, Colorado, and New Mexico, which were part of the Mexican Cession.

5. Middle Middle Region:
- Event: Louisiana Purchase (1803)
- Reason: This region represents the central part of the country, which was greatly expanded by the Louisiana Purchase.

6. Middle Right Region:
- Event: Treaty of Paris (1783)
- Reason: This region includes the central and eastern parts of the country, which were expanded beyond the Appalachian Mountains after the Revolutionary War.

7. Bottom Left Region:
- Event: Gadsden Purchase (1853)
- Reason: This region represents the small strip of land in the extreme southern part of the Southwest.

8. Bottom Middle Region:
- Event: Texas Annexation (1845)
- Reason: This region includes Texas, which was annexed as a state.

9. Bottom Right Region:
- Event: Florida Treaty (1819)
- Reason: This region includes Florida, which was acquired through the Florida Treaty.

10. Eastern Most Region:
- Event: Original 13 Colonies
- Reason: This region represents the easternmost part of the country, where the original 13 colonies were located.

Step 3: Color Each Region

Once the regions are labeled, you can color them using different colors to visually distinguish each area. Use a legend or key to indicate which color corresponds to which event.

Final Answer

Here is the labeled map:

1. Top Left: Oregon Treaty (1846)
2. Top Middle: Treaty 49th Parallel (1818)
3. Top Right: British Cession (1842)
4. Middle Left: Mexican Cession (1848)
5. Middle Middle: Louisiana Purchase (1803)
6. Middle Right: Treaty of Paris (1783)
7. Bottom Left: Gadsden Purchase (1853)
8. Bottom Middle: Texas Annexation (1845)
9. Bottom Right: Florida Treaty (1819)
10. Eastern Most: Original 13 Colonies
