Megacities and Informal SettlementsActivities & Teaching Strategies
Active learning turns abstract megacity statistics into lived experience. Students move from reading about informal settlements to analyzing real photos, role-playing urban planners, and testing their own projections, which builds empathy and critical thinking that passive lessons can’t match.
Learning Objectives
- 1Analyze the primary push and pull factors driving rural-to-urban migration in megacities of the Global South.
- 2Compare and contrast the challenges of providing basic services (water, sanitation, housing) in formal versus informal urban settlements.
- 3Evaluate the role of informal economies in supporting the livelihoods of residents and contributing to the broader urban economy.
- 4Propose and justify strategies for sustainable urban development that address the needs of rapidly growing megacities.

Ready-to-Use Activities
Gallery Walk: Informal Settlements Around the World
Post satellite images and short profiles of informal settlements , Dharavi (Mumbai), Kibera (Nairobi), Rocinha (Rio de Janeiro), and Makoko (Lagos) , around the room. Each station includes a guiding question comparing infrastructure, economic activity, and geographic location. Student pairs record observations, then the class identifies shared patterns across all four cases.
Prepare & details
Explain why urban growth is outstripping infrastructure in cities like Lagos or Mumbai.
Facilitation Tip: For the Gallery Walk, place images with captions that include population density, employment sectors, and infrastructure gaps for students to analyze in pairs first.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Simulation Game: Urban Planning Council Meeting
Assign students roles , municipal government, NGO housing advocate, slum resident, real estate developer , and give each role group a data brief with population projections, land maps, and budget constraints. Groups negotiate a plan to address housing shortages in a fictional megacity, then defend their decisions to the full council.
Prepare & details
Analyze how informal economies in slums support the wider city economy.
Facilitation Tip: When running the Urban Planning Council Meeting, give each role (developer, resident, mayor) a 1-minute opening statement with their priorities so the debate stays focused on trade-offs.
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
Think-Pair-Share: Myth vs. Reality of Informal Economies
Students individually read a short excerpt contrasting media portrayals of informal settlements with research on their economic vitality , for example, Dharavi's $1 billion recycling industry. Pairs then discuss whether the term 'informal' economy is accurate before sharing conclusions with the class.
Prepare & details
Predict what strategies can be used to provide basic services to millions of new urban residents.
Facilitation Tip: In the Think-Pair-Share, provide a table with columns for ‘economic activity’ and ‘social role’ to guide students in identifying patterns in the informal economy examples.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Data Analysis: Projecting Megacity Growth
Using UN urbanization data tables, small groups chart projected population growth for five megacities through 2050 and identify which are growing fastest. Groups must determine what geographic factors , coastal access, proximity to export zones, historical capital city status , explain those growth rates.
Prepare & details
Explain why urban growth is outstripping infrastructure in cities like Lagos or Mumbai.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Teaching This Topic
Teach megacity topics by grounding abstract ideas in concrete cases. Research shows role-play and image analysis help students recognize informal settlements as interconnected systems, not isolated slums. Avoid over-relying on lectures about poverty statistics; instead, let students discover the complexity through data and dialogue.
What to Expect
Successful learning looks like students questioning stereotypes about informal settlements, using data to justify urban planning choices, and explaining how self-built economies serve the city. They should move beyond seeing these areas as problems to recognizing them as parts of urban systems.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring the Think-Pair-Share activity, watch for students who describe informal settlements only in terms of poverty or disorder.
What to Teach Instead
Redirect their attention to the provided micro-economy case cards (e.g., Dharavi’s recycling cooperatives) and ask them to identify one specific good or service these communities provide to the formal city, then explain how that changes their view.
Common MisconceptionDuring the Simulation: Urban Planning Council Meeting, listen for arguments that frame informal settlements as problems to be removed or ignored.
What to Teach Instead
Prompt students to reference the economic integration data displayed on the board (e.g., ‘30% of formal city labor comes from these areas’) and ask them to propose solutions that work with rather than against these communities.
Common MisconceptionDuring the Gallery Walk, note when students assume informal settlements are temporary or illegal.
What to Teach Instead
Point to the timeline images showing 20-year-old settlements with multi-generational families and ask students to explain how long-term residency changes their understanding of land tenure and belonging.
Assessment Ideas
After the Data Analysis activity, provide a fictional megacity map with 2035 population projections and ask students to write two challenges and two potential solutions, using their projected density data to justify their choices.
During the Think-Pair-Share activity, facilitate a whole-class discussion using the prompt: ‘Are informal settlements symptoms of failed planning or creative adaptations?’ Have students reference specific case data from the Gallery Walk images to support their stances.
After the Simulation: Urban Planning Council Meeting, display a fictional megacity map and ask students to label three new public infrastructure sites (school, hospital, transit), justifying each choice based on population density and existing settlement patterns they observed during the activity.
Extensions & Scaffolding
- Challenge early finishers to design a policy brief for a megacity mayor proposing one formal-informal partnership project based on their Gallery Walk findings.
- Scaffolding for struggling students: provide sentence stems like ‘This settlement functions as a ______ because ______’ and a word bank of economy types (recycling, retail, food) during the Think-Pair-Share.
- Deeper exploration: ask pairs to compare informal settlement labor data from two different megacities and present a 2-minute summary of key similarities and differences.
Key Vocabulary
| Megacity | An urban agglomeration with a population of ten million or more people, often experiencing rapid growth. |
| Informal Settlement | A residential area, often unplanned and lacking secure tenure, where housing and infrastructure are inadequate and basic services are limited or absent. |
| Urbanization | The process of population shift from rural to urban areas, the corresponding decrease in the proportion of people living in rural areas, and the ways in which societies adapt to this change. |
| Infrastructure | The basic physical and organizational structures and facilities (e.g., buildings, roads, power supplies) needed for the operation of a society or enterprise. |
| Informal Economy | Economic activities and the people who participate in them that are not regulated or protected by the state, often including street vending, small-scale manufacturing, and domestic work. |
