Despite their increasing population, many teacher preparation programs have yet to provide adequate preparation for teaching Emergent Bilinguals (EBs). To respond to this situation and to the high demand for effective teachers of EBs, we investigated how preservice teachers (PSTs) adapt mathematics lesson plans for EBs. Twenty-one secondary mathematics PSTs, enrolled in two university-based programs, participated in this study and developed lesson plans for EBs. Our analysis revealed that although the PSTs frequently implemented visuals and group work strategies for EBs, they need to better integrate EBs' funds of knowledge and academic language support.
