teach middle school social studies, and during any given unit, I keep books having to do with the topic we are studying on the chalk holder section of the chalkboard, so that they are visible to my students, and maybe capture their attention. If we have silent reading or quiet time while other students are finishing tests, etc., this series is the one that my students reach for. They go through these books over and over, and I see a lot of pointing to share the pictures and text. I almost didn't get the series, because I thought it might be too young, but I know that my 11-13 year olds choose these books over all others.
