Barbara Shreve has spent 12 years teaching in high school math classrooms, including 10 years at Railside High School where she also served as department co-chair. Her experiences with students and colleagues at Railside deepened her passion for investigating how students talk and work together, and how teachers and students together build environments where every student has the opportunity to make sense of important mathematics content. She currently works as a math specialist in Oakland Unified School District, supporting teacher leaders and teams of teachers in their work with the Common Core State Standards.
