Smith and Stein (U. of Pittsburgh) enumerate five practices for facilitating productive math discussions that are rooted in student thinking and that make student-centered approaches accessible to and manageable for more teachers: anticipating students' solutions to a task; monitoring in-class, real-time work on the task; selecting approaches and students to share them; sequencing students' presentations purposefully; and connecting approaches with the underlying math. They also discuss the need to set clear learning goals and identify a task consistent with those goals; the types of questions teachers can ask to challenge thinking and what they can do to promote participation in whole-class discussions; how the model fits in the context of preparing for a lesson, with a tool for comprehensive lesson planning; and how teachers can work with colleagues, coaches, and school leaders to ensure they have the necessary time, materials, and access to expertise. The book ends with a professional development guide. There is no index. Annotation ©2011 Book News, Inc., Portland, OR (booknews.com) Read Less
