Simulation Game: The President's Dilemma

Students act as advisors to Jefferson. They are presented with the offer to buy Louisiana but must weigh the constitutional concerns (it's not in the text) against the strategic benefits (control of the Mississippi), eventually deciding whether to proceed.

Prepare & details

Explain the circumstances that led to the Louisiana Purchase.

Facilitation Tip: During The President's Dilemma simulation, assign students roles as advisors, farmers, or diplomats so they must defend their positions using historical evidence from provided documents.

Setup: Flexible space for group stations

Materials: Role cards with goals/resources, Game currency or tokens, Round tracker

Inquiry Circle: The Corps of Discovery Journals

Groups are given excerpts from Lewis and Clark's journals and sketches. They must identify a new plant/animal, a geographical challenge, and a specific interaction with a Native American tribe, creating a 'field report' for the President.

Prepare & details

Analyze the constitutional dilemma Jefferson faced regarding the purchase.

Facilitation Tip: While creating the Corps of Discovery Journals, require each group to include at least one primary-source quote about Native American diplomacy or a geographical challenge.

Setup: Groups at tables with access to source materials

Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template

Think-Pair-Share: The Role of Sacagawea

Students read about Sacagawea's contributions as a translator and guide. They discuss in pairs how the expedition might have been different without her and why her presence was a signal of peace to other tribes.

Prepare & details

Predict the long-term impact of the Louisiana Purchase on U.S. expansion and Native American lands.

Facilitation Tip: For The Role of Sacagawea Think-Pair-Share, give students a graphic organizer with sentence stems like 'Sacagawea helped the expedition by...' to structure their evidence-based responses.

Setup: Standard classroom seating; students turn to a neighbor

Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs

Teaching This Topic

Experienced teachers approach this topic by framing the Louisiana Purchase as a case study in compromise, where strict constitutionalism met geopolitical necessity. Avoid presenting it as a simple success story, and instead focus on the consequences for Native nations and the contested nature of westward expansion. Research shows that using role-play and journaling helps students grasp the human dimensions of historical decisions.

What to Expect

Successful learning looks like students explaining Jefferson’s constitutional dilemma in their own words, citing specific evidence from the Corps of Discovery Journals to describe the expedition’s goals, and analyzing Sacagawea’s role using evidence from the Think-Pair-Share discussion.

Watch Out for These Misconceptions

Common Misconception

During The President's Dilemma, watch for students who simplify the Louisiana Purchase as just a land sale.

What to Teach Instead

After the simulation, ask each group to share one geopolitical factor they considered (e.g., France’s war with Britain, Spain’s earlier claims) and write it on the board to highlight complexity.

Common Misconception

During The Corps of Discovery Journals, watch for students who describe the West as 'empty' or 'unexplored' before the expedition.

What to Teach Instead

Require groups to include a section in their journals titled 'Who Was Already Here?' with details about Native nations or French/Spanish traders they learned about in their research.

Assessment Ideas

Exit Ticket

After The President's Dilemma, give students a card with the prompt 'What was Jefferson’s constitutional dilemma?' and collect responses to check for understanding of Article II versus practical governance.

Discussion Prompt

After The Role of Sacagawea Think-Pair-Share, facilitate a class discussion where students must support their arguments about her significance with evidence from the journals or primary sources, citing at least one specific detail.

Quick Check

During The Corps of Discovery Journals activity, circulate and ask each group to identify one geographical feature (e.g., Missouri River, Rocky Mountains) and explain its significance for exploration or settlement, noting their responses for assessment.

Extensions & Scaffolding

• Challenge early finishers to draft a letter from a Native American leader responding to Lewis and Clark’s arrival, using details from the Corps of Discovery Journals.
• Scaffolding for struggling students: Provide sentence starters for the Think-Pair-Share and pre-highlight key phrases in the primary sources used in The Corps of Discovery Journals.
• Deeper exploration: Have students compare Jefferson’s initial instructions to Lewis with the actual outcomes of the expedition, using their journals as evidence.
