Scholars suggest that culturally responsive instructional supervision (CRIS) is an important component of equitable teaching practices in schools. This fictional case study details the experiences of a fifth-grade team who, along with their principal and their instructional coach, perform a discourse analysis of their own mathematics lessons to diagnose the equity gaps in their teaching and make necessary adjustments. The case narrative highlights the need for equitable teaching practices in the mathematics classroom and the potential needs of school leaders as they work to create more equitable learning environments in their schools through the use of CRIS.
