With a unique focus on grades 4 and 5, this book explains how to design and implement a research-based reading program that helps all students build major literacy skills (word recognition, fluency, vocabulary, and comprehension). The expert authors present ready-to-use activities, strategies, and lesson plans, along with detailed guidance for assessing students and providing instruction in differentiated small groups. Teachers get a clear understanding of how differentiation works in a tiered response-to-intervention model and how it aligns with the Common Core standards. In a convenient large-size format, the book includes extensive reproducible checklists and forms.
