Objectives:
- Describe the territorial expansion of the United States before the Civil War.
- Analyze the concept of Manifest Destiny.
Scene 1 — Engage
Student Activity
Students read an introduction explaining how the United States expanded westward in the early 1800s and how migration, transportation, and economic opportunities shaped growth. They review the online timeline A territorial history of the United States, focusing on 1800–1850, and then contribute to a class table by posting at least one question they have about territorial expansion during this period.
Teacher Moves
Present the lesson overview, key vocabulary (land grant, debt, annex), and objectives. Guide students through the timeline, then review their posted questions to gauge prior knowledge and interests. Select a few questions to highlight as guiding questions for the experience before moving the class to the next scene.
Scene 2 — Explore
Student Activity
Students read narrative text about Spanish and Mexican control of Texas, U.S. settlement encouraged by land grants, the growth of the Anglo-American population, the Texas Revolution, the Republic of Texas, and debates over annexation and slavery. They then answer multiple-choice questions about why settlers moved to Texas, why many Texans wanted U.S. statehood, and why Congress hesitated to annex Texas.
Teacher Moves
Monitor student responses to the questions and provide feedback. If needed, summarize the key ideas: many Americans moved to Texas for cheap land (often to escape debt), many still considered themselves Americans and wanted Texas to join the United States, and Congress delayed annexation largely because it did not want to add another slave state. Clarify any misconceptions before advancing.
Scene 3 — Explain
Student Activity
Students examine a map of U.S. states and territories in 1850 and read about how California shifted from a Spanish colony to Mexican territory, was ceded to the United States after the U.S.-Mexican War, experienced the Gold Rush, and quickly grew in population before becoming a state in 1850. Using a graphic organizer, they create a brief timeline of major events in California’s path to statehood. Students then return to the online timeline and watch the short video “The Westward Trails” to learn about the Oregon Trail and related migration routes, and finally post a description of the Oregon Trail in their own words.
Teacher Moves
Support students as they construct their California timelines, prompting them to include key events and correct sequence. Use the teacher example list to check for completeness. After students view the video and describe the Oregon Trail, share one or more strong responses with the class and summarize important details about the trail’s route, length, duration, and dangers, as well as other westward trails mentioned in the video.
Scene 4 — Elaborate
Student Activity
Students view the painting American Progress and read an explanation of Manifest Destiny as the belief that U.S. expansion from the Atlantic to the Pacific was inevitable. They contribute to a word cloud by naming objects or details in the painting that represent Manifest Destiny. Next, they choose one item from the painting and post an explanation of how it symbolizes Manifest Destiny, then read classmates’ posts and respond to at least two with questions or positive comments.
Teacher Moves
Guide students in closely observing the painting and connecting visual details to the idea of Manifest Destiny. Use sample responses (such as covered wagons, trains, farms, American Indians, and ships) to prompt deeper analysis. Encourage constructive peer feedback on the discussion wall and help students refine their explanations to clearly link specific imagery to the broader concept of U.S. expansion.
Scene 5 — Evaluate
Student Activity
Students complete the exit quiz by answering all the questions.
Teacher Moves
Facilitate the assessment and use student data to evaluate understanding, address misconceptions, and identify areas for growth.
