This book is the first in a new series from Carol Ann Tomlinson and Caroline Cunningham Eidson exploring how real teachers incorporate differentiation principles and strategies throughout an entire instructional unit. Focusing on the middle grades, but applicable at all levels, Differentiation in Practice, Grades 5-9 will teach anyone interested in designing and implementing differentiated curriculum how to do so or how to do so more effectively. Included are * Annotated lesson plans for differentiated units in social studies, language arts, science, mathematics, and world/foreign language. * Samples of differentiated worksheets, product assignments, rubrics, and homework handouts. * An overview of the essential elements of differentiated instruction and guidelines for using the book as a learning tool. * An extended glossary and recommended readings for further exploration of key ideas and strategies. Each unit highlights underlying standards, delineates learning goals, and takes you step by step through the instructional process. Unit developers provide running commentary on their use of flexible grouping and pacing, tiered assignments and assessments, negotiated criteria, and numerous other strategies. The models and insight presented will inform your own differentiation efforts and help you meet the challenge of mixed-ability classrooms with academically responsive curriculum appropriate for all learners.
