In the United States, mathematics is a barrier that prevents many students from reaching their educational goals. Research shows that math is a significant contributor to education equity gaps.1 Students have differential access to quality math curricula and quality teachers, and the mathematics course sequences traditionally offered in schools and colleges fail to serve most students. Too often, mathematics serves as a gatekeeper that negatively affects primarily students who are Black, Latinx, or Indigenous, or who come from low-income backgrounds.
