In this practical and accessible book, Rick Wormeli walks middle-school teachers through a differentiated lesson from start to finish, detailing what steps to take before, during, and after to deepen connections for students. At each stage, Rick offers time-tested strategies and reflective advice about reaching a wide range of learners within the same classroom. He presents annotated models of effective differentiated instruction, including tiering, flexible groupings, and adjustments based on formative assessments. Through extensive interdisciplinary examples, teachers also learn how to extend these processes to any subject, and any classroom.
