As I stated in my update, this text can be quite repetitive, but it is done so for a good reason. There is much more behind teaching 5th to 9th graders than one would think. And yes, the last year of elementary school and the first year of high school are considered "middle grades" because they are a time of transition.
Middle -schoolers (6th through 8th) get a bad reputation. I have been guilty of sharing the frustration I have felt with "babyish" 6th-graders, the lack of common sense from 7th-graders, and the "they think they're so grown" attitude of 8th-graders. What I forget, at times, is the fact that those behaviors are typical for that age range. So I have to adjust my expectations while being their social, as well as, academic mentor.
I do plan on rereading this from cover to cover. I only wish we had the video components to go with it.
