Ethical Mapping: Bias and RepresentationActivities & Teaching Strategies
Active learning engages students directly with the materials of bias, so they experience firsthand how cartography shapes perception rather than just hearing about it. When pupils measure, annotate, and redesign maps themselves, the abstract concept of representation becomes tangible and memorable.
Projection Comparison: Mercator vs. Gall-Peters
Students compare world maps using the Mercator and Gall-Peters projections side-by-side. They record observations about the relative sizes of continents and countries, discussing which projection seems more accurate and why.
Prepare & details
Analyze how map projections can perpetuate geographical biases.
Facilitation Tip: During the Debate Circle, assign roles like historian, cartographer, and policymaker to ensure every voice is heard and perspectives are grounded in evidence.
Setup: Chairs arranged in two concentric circles
Materials: Discussion question/prompt (projected), Observation rubric for outer circle
Historical Map Analysis: Colonial Portrayals
Examine a historical map depicting a region affected by colonialism. Students identify elements that reveal the mapmaker's perspective, such as place names, borders, or the depiction of local populations.
Prepare & details
Critique historical maps for their representation of different cultures or regions.
Setup: Chairs arranged in two concentric circles
Materials: Discussion question/prompt (projected), Observation rubric for outer circle
Community Mapping Project: Whose Land Is It?
Students research and map local indigenous territories or significant cultural landmarks. They discuss how their map differs from official maps and why diverse perspectives are important for representing their community.
Prepare & details
Justify the importance of diverse perspectives in modern cartography.
Setup: Chairs arranged in two concentric circles
Materials: Discussion question/prompt (projected), Observation rubric for outer circle
Teaching This Topic
Teachers should emphasize that maps are arguments, not facts. Avoid presenting projections as neutral tools; instead, frame them as evidence of historical and political choices. Research shows that students grasp bias better when they actively reconstruct maps rather than passively observe them.
What to Expect
Successful learning looks like students questioning the neutrality of maps, identifying specific distortions, and proposing alternative designs that center equity. They should articulate how projection choices influence global narratives and feel empowered to critique power structures in visual media.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Gallery Walk, watch for students who assume all maps are equally trustworthy because they look official or colorful.
What to Teach Instead
Prompt them to compare labels, symbols, and scale across stations, asking: 'Who benefits from this version of the map? Who is left out?' Use their sticky notes to highlight discrepancies.
Common MisconceptionDuring Projection Pairs, watch for students who focus only on size differences without linking them to power.
What to Teach Instead
Have them calculate the ratio of area changes between regions and discuss what it would mean if one country appeared five times larger than another on a classroom wall map.
Common MisconceptionDuring Redesign Challenge, watch for students who replicate existing biases in their own maps without realizing it.
What to Teach Instead
Ask them to swap drafts with peers for a 'bias audit' using a checklist: 'Does every territory have equal detail? Are labels neutral?' Discuss findings in small groups.
Assessment Ideas
After Projection Pairs, provide the Mercator and Peters maps again and ask students to write one sentence comparing Africa’s size on each and one sentence explaining why the difference matters for global perceptions.
During Gallery Walk, present students with a historical map of Ireland from the 18th century and ask: 'What does this map show about how people at that time viewed Ireland’s place in the world? What might be missing from this map, and why?' Facilitate a class discussion on what these omissions reveal.
After the Redesign Challenge, show students a map of a fictional continent and ask them to identify one element that might represent a bias (e.g., a capital city shown much larger than others). Have them explain their reasoning in one to two sentences.
Extensions & Scaffolding
- Challenge early finishers to create a short comic strip showing how a map’s bias might influence a traveler’s decisions about routes or destinations.
- Scaffolding for struggling students: Provide partially redrawn maps with guided labels (e.g., 'This city is enlarged because...') to lower the cognitive load.
- Deeper exploration: Invite students to research a projection’s origin story, then present how its creator’s context influenced the design.
