In response to urgent calls for teaching that is culturally affirming, scholars have developed a myriad of images of culturally sustaining (and related) pedagogies (CSPs). However, for maths teachers, CSPs remain elusive, in part because these images are typically content-neutral and their applicability to practice opaque. In this paper, I synthesize research to help conceptualize and clarify what CSPs may look like specifically in mathematics classrooms. I offer a framework for CSPs in mathematics comprised of four dimensions: (1) anti-assimilationism, (2) strengths-based teaching, (3) power and justice, and (4) affirming identities.
