How do teachers develop and use political knowledge to create equitable and inclusive conditions for and with disabled students, particularly disabled students of color? In this essay, we build on concepts of political teacher knowledge in mathematics education, critical inclusive mathematics education and disability studies to explore teacher knowledges that support disabled students' mathematical learning. We focus on four aspects of political knowledge for teaching mathematics: (1) knowledge as relational and unfolding over time, (2) understanding and negotiating the political contexts in which we teach mathematics, (3) deconstructing deficit discourses about marginalized students, and (4) learning to creatively resist the systems for and with our students. To develop our theoretical analysis, we use a counterstory of a middle school Latino student named Luis and his Latina mathematics teacher, Ms. Marquez. Our aim is to open up discussions in mathematics teacher educational research about the politics at play in teaching inclusive mathematics.
