Welcome to the ATMALA Newsletter. We are made up of 20 middle and high school math teachers who, together with CSU Fullerton faculty, are focused on transforming mathematics classrooms to meet the needs of all students. We believe in fostering culturally responsive mathematics teaching, where the content builds on students' prior knowledge and relates to their cultural, linguistic, and community experiences, improving students' access, interest and success with mathematics. We hope to inspire other educators to take an active role in transforming mathematics education.
