This sustained professional development course is designed to support teachers who aim to provide their students with a connected and conceptual understanding of math content. Through an introductory three-day, in-person workshop; a one-day, concluding in-person workshop; and ongoing coaching, this course will help math teachers provide increased opportunities for students to learn by increasing their use of high cognitive demand tasks and mathematical talk in their classrooms. Teachers will become more closely acquainted with the disciplinary practices described by the Common Core State Standards and Next Generation Science Standards, as well as the 5 Practices for Orchestrating Productive Mathematics DiscussionsUsing these resources as a framework, teachers will learn to engage students in authentic mathematics in ways that are aligned with the changing landscape of education in the U.S.
