"This book makes the five practices accessible for high school mathematics teachers. Teachers will see themselves and their classrooms throughout the book. High school mathematics departments and teams can use this book as a framework for engaging professional collaboration. I am particularly excited that this book situates the five practices as ambitious and equitable practices."Robert Q. Berry, IIINCTM President 2018-2020Samuel Braley Gray Professor of Mathematics Education, University of VirginiaTake a deeper dive into understanding the five practices-anticipating, monitoring, selecting, sequencing, and connecting-for facilitating productive mathematical conversations in your high school classrooms and learn to apply them with confidence. This follow-up to the modern classic, 5 Practices for Orchestrating Productive Mathematics Discussions, shows the five practices in action in high school classrooms and empowers teachers to be prepared for and overcome the challenges common to orchestrating math discussions.The chapters unpack the five practices and guide teachers to a deeper understanding of how to use each practice effectively in an inquiry-oriented classroom. This book will help you launch meaningful mathematical discussion through Key questions to set learning goals, identify high-level tasks, anticipate student responses, and develop targeted assessing and advancing questions that jumpstart productive discussion-before class begins Video excerpts from real high school classrooms that vividly illustrate the five practices in action and include built-in opportunities for you to consider effective ways to monitor students' ideas, and successful approaches for selecting, sequencing, and connecting students' ideas during instruction "Pause and Consider" prompts that help you reflect on an issue-and, in some cases, draw on your own classroom experience-prior to reading more about it "Linking To Your Own Instruction" sections help you implement the five practices with confidence in your own instructionThe book and companion website provide an array of resources including planning templates, sample lesson plans, completed monitoring tools, and mathematical tasks. Enhance your fluency in the five practices to bring powerful discussions of mathematical concepts to life in your classroom.
