Gerrymandering and Electoral DistrictsActivities & Teaching Strategies
Active learning works for gerrymandering because spatial data becomes meaningful when students create and manipulate maps themselves. Drawing districts forces them to confront the tension between geography and political outcomes in a tangible way, building critical thinking about power and representation.
Learning Objectives
- 1Analyze how the geographic shape and population distribution of a voting district can be manipulated to favor a specific political party.
- 2Evaluate the arguments for and against different methods of drawing electoral boundaries, such as independent commissions versus legislative control.
- 3Design a hypothetical electoral map for a given region, justifying boundary choices based on principles of representation and fairness.
- 4Compare the effects of 'packing' and 'cracking' strategies on election outcomes using simulated data.
- 5Explain the legal and political challenges associated with gerrymandering in the United States, referencing key court decisions.

Simulation Game: Draw the Districts
Provide each small group with a grid representing a hypothetical state with two parties distributed across precincts. Groups must draw five districts following different goals: maximize Party A wins, maximize Party B wins, or create the most competitive districts possible. Groups compare results and discuss what principles should govern real redistricting.
Prepare & details
Explain how the shape of a voting district can determine the outcome of an election.
Facilitation Tip: During the Simulation, circulate to listen for students describing 'packing' or 'cracking' as they draw, rather than just focusing on shape.
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
Gallery Walk: Real Gerrymanders
Post large printouts of notorious gerrymandered districts around the room (North Carolina's 12th, Maryland's 6th, Illinois's 4th). Students rotate in pairs, annotating each map with the packing or cracking strategy used and the demographic or political group targeted. Pairs share findings in a whole-class debrief.
Prepare & details
Evaluate who should have the power to draw electoral boundaries to ensure fairness.
Facilitation Tip: For the Gallery Walk, assign small groups to focus on one case map and prepare a two-minute analysis of the district's partisan impact.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Structured Academic Controversy: Who Should Draw the Maps?
Students research four redistricting models: state legislatures, independent commissions, courts, and algorithmic methods. Each group advocates for one model, presents evidence, then switches sides before the class reaches a consensus position on the best approach.
Prepare & details
Design a fair electoral map for a hypothetical region.
Facilitation Tip: In the Structured Academic Controversy, give teams five minutes to prepare their strongest argument before switching sides for rebuttal.
Setup: Pairs of desks facing each other
Materials: Position briefs (both sides), Note-taking template, Consensus statement template
Think-Pair-Share: Analyzing Your Own State
Students individually research the current congressional district map of their own state using publicly available mapping tools. They identify any unusual shapes, then pair with a classmate to hypothesize the strategic logic. Pairs share their most striking finding with the class.
Prepare & details
Explain how the shape of a voting district can determine the outcome of an election.
Facilitation Tip: During the Think-Pair-Share, have students record their partner's state analysis on a shared document for later reference.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Teaching This Topic
Teachers approach this topic by balancing data analysis with ethical debate, avoiding the trap of presenting gerrymandering as a simple left-right issue. Use real maps with demographic overlays so students see how geography, population, and politics interact. Emphasize that solutions require structural changes, not just partisan blame. Research shows students grasp abstract concepts like 'packing' better when they see it visually and then discuss its human impact.
What to Expect
Successful learning looks like students confidently explaining how district shapes influence election results and defending their views on who should draw the maps. They should recognize gerrymandering strategies in real examples and articulate structural alternatives.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring the Simulation: Draw the Districts, students may assume gerrymandering only benefits Republicans.
What to Teach Instead
During the Simulation, deliberately include maps from states like Maryland and Illinois where Democrats have gerrymandered, having students calculate seat advantages in both parties' maps to see the practice is bipartisan.
Common MisconceptionDuring the Case Study Gallery Walk: Real Gerrymanders, students might interpret any oddly shaped district as gerrymandered.
What to Teach Instead
During the Gallery Walk, give students a data sheet for each case that includes Voting Rights Act requirements and minority community locations, so they learn to distinguish legitimate legal districts from partisan manipulation.
Common MisconceptionDuring the Structured Academic Controversy: Who Should Draw the Maps?, students may believe the Supreme Court has fixed the gerrymandering problem.
What to Teach Instead
During the Controversy, provide the Rucho v. Common Cause decision summary and have teams research state-level solutions like independent commissions, making clear federal courts no longer oversee partisan gerrymanders.
Assessment Ideas
After the Simulation: Draw the Districts, show students two maps of a hypothetical state and ask them to identify at least two visual clues on the gerrymandered map and explain why those clues indicate manipulation.
After the Structured Academic Controversy: Who Should Draw the Maps?, facilitate a class debate using the prompt: 'Who should have the ultimate authority to draw electoral boundaries in the US: elected officials, an independent commission, or the courts? Why?' Have students support their positions with evidence from their research on state processes.
During the Think-Pair-Share: Analyzing Your Own State, ask students to write a short paragraph explaining the difference between 'packing' and 'cracking' and provide one example of how each strategy could impact election results in a specific district.
Extensions & Scaffolding
- Challenge early finishers to design a fair redistricting algorithm and test it on their state map.
- Scaffolding for struggling students: Provide a partially drawn map with key communities pre-labeled before they begin their own districts.
- Deeper exploration: Assign students to research how their state's redistricting process works and present findings to the class.
Key Vocabulary
| Gerrymandering | The practice of drawing electoral district boundaries to favor one political party or group over another, often resulting in oddly shaped districts. |
| Electoral District | A geographic area represented by one or more elected officials, used for the purpose of voting in elections. |
| Packing | A gerrymandering technique that concentrates voters of the opposing party into a single district, ensuring they win that district overwhelmingly but lose elsewhere. |
| Cracking | A gerrymandering technique that divides voters of the opposing party across multiple districts, diluting their voting power in each. |
| Redistricting | The process of redrawing electoral district boundaries, typically after a census, to reflect population changes and ensure equal representation. |
