🌟🌟🌟🌟🌟5 stars!<br>This book deserves to sit on every math teachers shelf with a bunch of quotes highlighted and a bunch of post it notes attached. It’s that good. If you want to have effective, engaging, differentiated small groups that will help students fully grasp the concept, this book is for you. To be honest, this book has been better than some professional developments I have attended. The videos really helped me to solidify what I read. Buy this book today!
