Challenges of Urban Growth

Active learning works for this topic because urban growth challenges are complex, interconnected problems that require students to analyze real-world contexts, collaborate on solutions, and confront their own assumptions. Students need to move beyond textbook definitions to see how infrastructure, policy, and social dynamics shape communities in concrete ways.

Activity 01

• Jigsaw
• 50 min · Small Groups

Jigsaw: Informal Settlements

Divide class into expert groups, each assigned a city like Kibera or Toronto's tent encampments. Groups research challenges using provided sources. Regroup into mixed teams to teach peers and compile a class summary poster.

Explain the challenges faced by residents of informal settlements.

Facilitation Tip

During Jigsaw Case Studies, assign each expert group a distinct informal settlement to analyze, then have them teach their findings to peers to ensure accountability and depth.

What to look for

Provide students with a scenario describing a rapidly growing city. Ask them to identify two key challenges related to urban growth from the lesson and propose one specific infrastructure improvement that could address one of these challenges.

Activity 02

• Problem-Based Learning
• 60 min · Pairs

Design Challenge: Green Urban Block

Pairs sketch a city block addressing infrastructure and inequality, incorporating bike lanes, community gardens, and affordable housing. Use graph paper and criteria checklists. Present designs to class for feedback.

Analyze how urban design can reduce the environmental footprint of city dwellers.

Facilitation Tip

In the Design Challenge, provide students with a blank site plan and a list of required elements, but leave the final design decisions open for them to justify.

What to look for

Facilitate a class discussion using the prompt: 'Imagine you are a city council member. How would you balance the need for economic development with the imperative to create equitable and sustainable living conditions for all residents, especially those in informal settlements?'

Activity 03

• 45 min · Whole Class

Role-Play Debate: Sprawl Solutions

Assign roles as residents, planners, or officials debating high-density vs. sprawl. Provide evidence cards on environmental and social impacts. Vote on best solution after structured arguments.

Design a sustainable urban planning solution for a specific challenge.

Facilitation Tip

For the Role-Play Debate, assign roles based on real stakeholder perspectives to push students beyond their own viewpoints.

What to look for

Present students with images or short case studies of different urban areas. Ask them to classify each area based on the presence or absence of key indicators of informal settlements or successful urban planning, such as sanitation access or green space availability.

Activity 04

• Problem-Based Learning
• 40 min · Pairs

Mapping Walk: Local Urban Pressures

Students map school neighbourhood for growth signs like traffic or green space gaps using phones or paper. Discuss findings in pairs and propose one fix per pair.

Explain the challenges faced by residents of informal settlements.

Facilitation Tip

On the Mapping Walk, give students a simple data collection sheet to record observations about local pressures like housing density or green space access.

A few notes on teaching this unit

Teachers should approach this topic by grounding abstract concepts in local examples first, then expanding globally to avoid overwhelming students with too much unfamiliar context. Use scaffolding to help students connect their prior knowledge of city life to the broader themes of migration and sustainability. Avoid rushing to solutions; instead, let students sit with the discomfort of unresolved challenges to build critical thinking. Research shows that students retain concepts better when they grapple with real dilemmas rather than hypothetical scenarios.

Successful learning looks like students explaining the root causes of urban challenges rather than just listing symptoms, designing solutions that balance human needs with environmental limits, and recognizing that progress requires both technological innovation and social equity. They should articulate trade-offs when proposing solutions and support their ideas with evidence from diverse sources.

Watch Out for These Misconceptions

• During Jigsaw Case Studies, watch for students assuming urban growth problems only happen in developing countries.

  Direct students to compare their case study data with local examples you provide, such as Toronto’s housing crisis or Montreal’s informal tent communities, and ask them to identify shared indicators like sanitation access or overcrowding.

• During Design Challenge, watch for students believing technology alone will solve urban infrastructure strains.

  Require students to include a section in their design brief explaining how social factors like affordability or policy gaps might limit the effectiveness of their proposed solutions.

• During Role-Play Debate, watch for students assuming informal settlements disappear with economic growth.

  During the debrief, ask groups to share evidence from their case studies showing how settlements persist despite growth, then prompt them to evaluate policy choices that could address these gaps.
