Many math educators are grappling with ways to make their instruction more culturally responsive to improve their students' feelings of belonging, perceptions of relevance, and academic learning outcomes. To learn more about how to facilitate the application of innovative and promising practices in math classrooms, a continuous improvement organization called Shift convened a group of 8th- to 10th-grade math educators from across the country in spring 2022 to develop and test change ideas at the intersection of culturally responsive pedagogy and math teaching. In this article are examples of how three educators designed and tested small, focused cycles of plan-do-study-acts (PDSAs) to result in deeper learning about what works in their contexts. By sharing change ideas that have worked, other educators can try them out and adapt them to their contexts.
