Congressional Redistricting & GerrymanderingActivities & Teaching Strategies
Active learning works well for this topic because redistricting and gerrymandering are abstract concepts best understood through concrete, hands-on experiences. Students need to see how line drawing creates real political outcomes, not just hear about it. When they move maps and debate outcomes, the stakes become visible and personal.
Learning Objectives
- 1Analyze census data to explain its role in reapportionment and redistricting.
- 2Evaluate the impact of gerrymandering techniques, such as 'packing' and 'cracking', on election outcomes.
- 3Compare and contrast the arguments for and against using independent commissions versus state legislatures for drawing district lines.
- 4Critique the effectiveness of judicial review in regulating partisan gerrymandering.
- 5Synthesize information to propose potential reforms for the redistricting process.

Simulation Game: The Redistricting Challenge
Give students a grid of 'voters' (Red and Blue). They must draw 5 districts. First, they must draw them to be 'fair.' Then, they must redraw them to ensure a 'Red' win, then a 'Blue' win, using the same data.
Prepare & details
Should independent commissions replace state legislatures in drawing district lines?
Facilitation Tip: During the Redistricting Challenge, circulate with colored pencils and encourage students to explain their map choices aloud to uncover their reasoning.
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
Think-Pair-Share: Independent Commissions
Students read about states that use independent commissions vs. those where the legislature draws the lines. They discuss the pros and cons of taking the power away from politicians and the impact on 'safe' vs. 'competitive' seats.
Prepare & details
How does gerrymandering contribute to political polarization?
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Gallery Walk: Gerrymander 'Art'
Display maps of the most oddly shaped districts in the US (e.g., the 'Goofy Kicking Donald Duck' district). Students must guess why the lines were drawn that way and what specific groups were being 'packed' or 'cracked.'
Prepare & details
Can 'packing and cracking' be effectively regulated by the courts?
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Teaching This Topic
Teachers should treat this topic as a case study in political power, not a dry civics lesson. Start with students’ lived experiences of representation, then build toward abstract concepts. Avoid getting bogged down in legal minutiae early; focus first on the human impact of district lines. Research shows that when students manipulate maps themselves, they retain concepts longer than through lecture alone.
What to Expect
Successful learning looks like students applying redistricting principles to real maps, identifying gerrymandering techniques in practice, and articulating the consequences for representation. They should move from confusion to clarity about how districts shape elections and governance. Evidence of understanding includes clear explanations of packing and cracking, not just memorization of definitions.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring the Redistricting Challenge, watch for students assuming gerrymandering is always illegal.
What to Teach Instead
Use the Rucho v. Common Cause case summary as a reference point during the simulation. After students draw maps, ask them to evaluate which ones would likely face legal challenges and why.
Common MisconceptionDuring the Gallery Walk of Gerrymander 'Art', watch for students thinking redistricting only affects Congress.
What to Teach Instead
Have students identify examples of gerrymandered city council or school board districts in the gallery. Ask them to explain how local lines shape their daily lives.
Assessment Ideas
After the Redistricting Challenge, collect the two district maps and one-sentence explanations. Look for clear evidence of packing and cracking, and logical connections between map shapes and political outcomes.
During the Think-Pair-Share on Independent Commissions, listen for students referencing evidence from the Rucho case or the gallery walk to support their arguments about who should control redistricting.
After the Gallery Walk, have students define gerrymandering on an index card and name one specific way it affects either voters or elected officials, using examples from the maps they viewed.
Extensions & Scaffolding
- Challenge: Ask students to research a recent gerrymandering case in their state, then present a 2-minute summary of the political and legal stakes.
- Scaffolding: Provide pre-drawn maps with key communities identified, so students focus on redistricting techniques rather than starting from scratch.
- Deeper exploration: Have students compare historical maps from their state to current ones, identifying shifts in district shapes and demographics over time.
Key Vocabulary
| Reapportionment | The process of reassigning the 435 seats in the U.S. House of Representatives to the states based on population changes determined by the decennial census. |
| Redistricting | The process of redrawing the boundaries of congressional districts within a state after reapportionment or due to population shifts, often influenced by political considerations. |
| Gerrymandering | The manipulation of electoral district boundaries to favor one political party, group, or incumbent, often resulting in oddly shaped districts. |
| Packing | A gerrymandering technique that concentrates voters of the opposing party into a single district, ensuring they win that district overwhelmingly but limiting their influence elsewhere. |
| Cracking | A gerrymandering technique that divides voters of the opposing party among multiple districts, diluting their voting power in each district. |
