Quick read with tons of practical advice. Written from the teacher's perspective, and teachers with clear experience. It connected so easily to my own teaching and experiences with ways to improve my work. I thought I had a really strong grasp on Responsive Classroom techniques, but I found that this clarified my understanding in general and corrected me on a few small things as well. It gave the big picture overview well and touched on so many little things in the day-to-day implementation, it feels like you can take this easily and apply it right away to your classroom. I would highly recommend this for any Elementary teacher, even if you've been teaching for a while.
