Active learning ideas

Defining Geographic Regions

Active learning works especially well for defining geographic regions because students often assume regions are fixed and objective. Handling real maps, student-generated examples, and debate materials helps them experience firsthand how regions are constructed and contested.

Activity 01

• Gallery Walk
• 40 min · Pairs

Gallery Walk: Where Does the South Begin?

Post six maps of the United States around the room, each using a different criterion to define 'the South' (Civil War boundaries, USDA plant hardiness zones, Baptist church density, dialect data, median income, or percentage of households with central air conditioning). Student pairs annotate each map, noting what it includes and excludes and what the mapmaker seemed to value as the defining criterion.

Construct a definition of a region beyond its physical boundaries.

Facilitation Tip

During the Gallery Walk, place provocative regional claims on posters so students physically move between perspectives rather than passively reading static definitions.

What to look for

Provide students with three scenarios: 1. The boundaries of the state of Colorado. 2. The delivery area for Domino's Pizza in your town. 3. The area commonly referred to as 'the South'. Ask students to identify each as a formal, functional, or perceptual region and briefly explain their reasoning for each.

Activity 02

• Hexagonal Thinking
• 55 min · Small Groups

Collaborative Mapping: Draw Your Region

Give student groups a blank U.S. map and a specific functional region to define (a major metro commuter zone, a media market, a watershed). Groups must select a central node, identify indicators for the boundary, and present their map to the class with a written rationale explaining which geographic criteria they used and why.

Compare formal, functional, and perceptual regions with real-world examples.

Facilitation Tip

In Collaborative Mapping, assign each group a different criterion (e.g., rainfall, commuter flows, dialect) to ensure they see how region boundaries change with purpose.

What to look for

Pose the question: 'If you were tasked with defining a region for a new national park, what criteria would you use, and what type of region would it be?' Facilitate a class discussion where students present their proposed criteria and defend their choice of region type, challenging each other's assumptions.

Activity 03

• Formal Debate
• 30 min · Whole Class

Formal Debate: Is the Midwest a Region?

Students receive three competing geographic definitions of 'the Midwest' and must argue for one using specific geographic criteria. The class then discusses what the persistent disagreement reveals about how all regional definitions work -- and what purpose the definition is designed to serve.

Justify the importance of regional analysis in understanding global interactions.

Facilitation Tip

For the Structured Debate, require each side to cite specific examples from maps, census data, or local knowledge to ground their claims in evidence.

What to look for

Present students with a list of geographic entities (e.g., Amazon River Basin, the Greater Los Angeles Area, the Rocky Mountains, the area where Spanish is spoken). Ask them to quickly label each as formal, functional, or perceptual and provide one key characteristic that supports their choice.

Activity 04

• Think-Pair-Share
• 20 min · Pairs

Think-Pair-Share: Formal, Functional, or Perceptual?

Present students with three real examples: a zip code, a school attendance boundary, and a neighborhood nickname like 'Midtown.' Students individually classify each as formal, functional, or perceptual with written justification, then compare with a partner and discuss cases where two classifications seem equally valid.

Construct a definition of a region beyond its physical boundaries.

Facilitation Tip

Use the Think-Pair-Share to push students beyond textbook definitions by asking them to compare a formal region’s map to a perceptual region’s lived experience.

What to look for

Provide students with three scenarios: 1. The boundaries of the state of Colorado. 2. The delivery area for Domino's Pizza in your town. 3. The area commonly referred to as 'the South'. Ask students to identify each as a formal, functional, or perceptual region and briefly explain their reasoning for each.

A few notes on teaching this unit

Teach this topic by treating regions as tools geographers use rather than natural facts on the ground. Start with students’ own mental maps and gradually introduce formal criteria, always asking which purpose each region serves and who benefits from its boundaries. Avoid presenting any single map as definitive; instead, compare multiple sources to show how regions are negotiated.

Successful students will move beyond memorizing boundaries and instead identify the criteria used to define regions, explain why regions shift depending on perspective, and justify their own regional classifications with evidence from maps and examples.

Watch Out for These Misconceptions

• During the Gallery Walk, watch for students who treat perceptual region claims as wrong or invalid because they lack official boundaries.

  Use the Gallery Walk posters to ask students to identify who created each claim and why, then discuss how different groups (e.g., tourism boards vs. sociologists) have different stakes in defining a region.

• During Collaborative Mapping, watch for students who assume their group’s region should match a textbook map exactly.

  Have groups present their maps, then ask peers to identify the criteria and trade-offs involved (e.g., "You included X town because of commuters, but excluded Y town because of voting patterns").

• During the Structured Debate, watch for students who dismiss perceptual regions as subjective and therefore unimportant.

  Use the debate to ask students to find measurable consequences of perceptual regions (e.g., property values, school funding) and explain how these effects make perceptual regions real and consequential.
