Differentiated instruction is the hallmark of good teaching. However, developing leveled materials and creating an organizational system to manage it all is an immense undertaking. In this comprehensive resource, veteran teacher and staff developer Margo Southall shares management tools along with hundreds of leveled activities that she has fine-tuned over the years. The result is an invaluable collection of research-based activities that enable teachers to match independent practice with students' needs in reading comprehension, fluency, word study, and writing. Moreover, Southall provides a workable framework that makes setting up the centers and tracking student progress simple. Includes dozens of planning sheets and record-keeping forms in addition to reproducible student pages. Meets Reading First and NCLB guidelines.
