Unit Plan 16 (Grade 8 Social Studies): Foreign Policy and Expansion
Investigate early U.S. diplomacy, trade conflicts, and territorial expansion—mapping global connections and interdependence while explaining causes and effects of key treaties, embargoes, and acquisitions.
Focus: Investigate early U.S. diplomacy, trade conflicts, and territorial growth—mapping global connections, modeling interdependence, and explaining causes/effects from treaties to embargoes.
Grade Level: 8
Subject Area: Social Studies (U.S. History • Geography • Economics • Civics)
Total Unit Duration: 5 sessions (one week), 50–60 minutes per session
I. Introduction
Students explore how the young United States navigated a world of empires and trade networks. Through maps, short sources, and quick simulations (Jay’s Treaty, Pinckney’s Treaty, Embargo Act, Louisiana Purchase, Adams–Onís), learners analyze how geography and economics shaped diplomatic choices, conflicts at sea, and expansion across the continent.
Essential Questions
- How did global trade networks and geography shape early U.S. foreign policy?
- Why did leaders choose neutrality, embargo, or treaty—and with what consequences?
- How did territorial growth change spatial connections, economies, and relations with Indigenous nations?
II. Objectives and Standards
Learning Objectives — Students will be able to:
- Describe and map spatial connections (diffusion, migration, trade routes) linking the U.S. to the Atlantic and interior rivers.
- Explain causes and effects of key foreign-policy decisions (neutrality, treaties, embargoes) and territorial acquisitions.
- Model trade and interdependence (imports/exports, blockades, supply disruptions) and predict stakeholder impacts.
- Evaluate competing policy options with claims, evidence, and counterarguments.
- Communicate conclusions with accurate maps, data visuals, and citations.
Standards Alignment — 8th Grade (C3-based custom)
- 8.C3.Geo.5: Describe spatial connections (diffusion, migration, trade) within the U.S. and with the world.
- 8.C3.Hist.2: Explain causes/effects for major developments (expansion, conflict, war).
- 8.C3.Econ.4: Explain trade and interdependence (domestic/foreign markets, wartime blockades).
Success Criteria — Student Language
- I can trace a trade route and explain how a policy changed flows of goods and people.
- I can build a cause–effect chain for a treaty, embargo, or territorial acquisition.
- I can show how interdependence makes some groups benefit and others lose during blockades or policy shifts.
