"Classroom Discussions: Seeing Math Discourse in Action, Grades K-6" provides preservice and inservice instructors, coaches and facilitators with real, classroom-based video examples that illustrate the principles and practices covered in the authors' best-selling book, "Classroom Discussions: Using Math Talk to Help Students Learn, Grade K-6, Second Edition". Ideally the three components--guide, DVD, and book--are used together. The video examples demonstrate how the talk tools described in the book can be used successfully in typical classrooms.
