How can students use mathematical modeling to reveal systems of power and privilege? This session invites participants to explore justice-centered modeling tasks on issues such as gerrymandering, housing, and climate change. Using authentic district maps and data, participants will analyze how mathematics can expose and challenge unfair voting boundaries. Grounded in critical mathematics education, the session highlights how modeling can cultivate students’ civic reasoning, agency, and ethical awareness. Participants will gain practical frameworks for designing learning experiences that position mathematics as a tool for understanding and transforming social realities.
