Unit Plan 14 (Grade 4 Social Studies): Building Communities

Focus: Analyze how early settlements in the state/region formed and grew around waterways and natural resources, and how people added human-made features (roads, bridges, canals, dams) that changed land use and community life. Students connect landforms, waterways, and climate to settlement patterns and basic causes and effects in community growth.

Grade Level: 4

Subject Area: Social Studies (History • Geography)

Total Unit Duration: 5 sessions (one week), 45–60 minutes per session

I. Introduction

Students explore how early communities in their state or region began as small settlements near rivers, lakes, crossroads, and resources and then grew into towns and cities. Using maps, early town images, and short texts, they look at how landforms, waterways, and climate shaped where people settled and how they used land. Students also examine how people built human-made features like roads, bridges, canals, and dams to support travel, trade, and energy, and how these features had both positive and negative impacts on communities and the environment.

Essential Questions

• Why did early settlers choose certain places—especially near waterways and resources—to build communities?
• How did landforms, waterways, and climate shape the location and growth of early settlements?
• What human-made features (roads, bridges, canals, dams) did people build to support growing communities, and what were their purposes and impacts?
• How did settlement growth affect Indigenous homelands, local resources, and interactions among groups?
• What cause-and-effect relationships can we see between environment, infrastructure, and community life?

II. Objectives and Standards

Learning Objectives — Students will be able to:

1. Identify at least two early settlements in the state/region and explain why people chose those locations (e.g., near rivers, fertile soil, resources, crossroads).
2. Describe how landforms, waterways, and climate influenced settlement patterns and basic land use (farming, trade, transportation).
3. Name and describe at least two human-made features (roads, bridges, canals, dams, early rail lines) and explain their purposes in supporting community growth.
4. Analyze at least one cause-and-effect chain showing how a natural feature plus a human-made feature led to changes in travel, trade, or daily life.
5. Recognize that early settlement and infrastructure changes impacted Indigenous communities and environmental conditions (access to land, waterways, resources).
6. Create a Community Growth Map & Cause–Effect Diagram that shows an early settlement, nearby natural features, added human-made features, and at least one cause–effect explanation of community growth and change.

Standards Alignment — 4th Grade (C3-based custom)

• 4.C3.Hist.4 — Explain exploration/settlement patterns and interactions among groups; note causes/effects.
  • Example: Causes of a trading post’s location and its impacts on nearby communities.
• 4.C3.Geo.3 — Describe landforms, waterways, climate/weather patterns; explain impacts on settlement and land use.
  • Example: Explain how a river valley encouraged trade and farming.
• 4.C3.Geo.4 — Explain human-made features/infrastructure (dams, canals, highways) and their purposes/impacts.
  • Example: Show how a dam changed energy, irrigation, and recreation.

Success Criteria — Student Language

• I can name at least two early settlements in our state/region and explain why people built communities there.
• I can describe how landforms, waterways, and climate affected where people lived and how they used the land.
• I can identify human-made features like roads, bridges, canals, or dams and explain how they helped communities grow.
• I can use cause-and-effect language to show how a natural feature and a human-made feature together changed travel, trade, or daily life.
• I can create a Community Growth Map & Diagram that clearly shows natural features, human-made features, and at least one cause–effect chain.
