Realizing Rigor in the Mathematics Classroom [PDF ebook] 

Rigor put within reach! Rigor: Everyone is talking about it, and now the Common Core has made it policy. But how exactly do you design a math classroom where achieving that goal is guaranteed? This first-of-its-kind guidebook will help teachers and leaders across the grades make that goal a reality. You’ll not only come to understand once and for all what rigor is, you’ll also learn how to consistently apply that ideal from math classroom to math classroom. Using their Proficiency Matrix as a framework, Hull, Harbin Miles, and Balka offer proven strategies for successful implementation of the CCSS mathematical practices-with practical tools you can use right away. Whether working individually or as part of a team, you’ll learn how to Define rigor in the context of each mathematical practice Identify and overcome potential issues and obstacles, including differentiating instruction, monitoring classrooms, and using data Relate specific roles and goals for students, teachers, math leaders, school leaders, and collaborative teams Use assessment tools to guide work and monitor progress With action checklists and record sheets, self-assessments, a teacher planning guide, and much more, this is the only resource you need to guide your team to rigor-and your students to achievement.
