I love this book and would honestly recommend for kindergarten through sixth grade and maybe even higher than that. This is one of those books that no matter which grade I teach I will want it in my classroom library. It is an insanely good, positive book! This book has so many lessons that could come out of it, but my favorite would be a lesson that designed around the classroom and helping the teacher. I saw an activity sheet that had four open ended questions that the students have to fill in. The first said "Places you would like to visit", second says, "People you would like to meet", third says, "Important people in your life", and the last one says, "Things you would like to learn". This would be a great beginning of the year activity to learn more about your students and you can even incorporate some of the stuff from their response into your classroom.
