If you are new to working with English Language Learners, then this book would be a valuable resource in your room. It is easy to read and several valuable strategies and ideas are given in each chapter. Haynes and Zacarian have several years of experience with ELLs and have written many books and articles on the topic. If you are not new to working with ELLs, this book is still valuable. I found myself taking notes on each chapter. It's always good to refresh your thinking and teaching.
I think this book would be a great option for a book study during the summer or beginning of the year. Some chapters I found very valuable were Reading Comprehension Instruction, Writing Instruction, Homework and Assessment, and Communicating with Families. There were several pages of guidelines in the Homework and Assessment chapter that I am planning on sharing with staff. After reading, I plan on sharing ideas from each chapter monthly with my staff next year.
