Absolutely loved it! Literature circles during which students get to choose what they read and how much they read. Groups come together to share and further increase their understanding of the book, depending on the book they currently read. So groupings change all the time. The book comes with much practical advice and many ready-to-use comprehension activities and assessment tools. Having just had the opportunity to see it in action with our Grade 3s, I know it works. This book has joined my list of all-time favorite titles of professional literature. Highly recommended!
