I picked this as a book for our Grade Three book club. My thinking was that it is the beginning of a series and if the super fast readers finish it they could continue on to the other books in the series. It's an older book (published in 1978) and there are a lot of things you just wouldn't see in books these days. The word stupid is used a lot, as well as fat and more. A lot of it is in the name of humor. It will be interesting to see if my students think it was funny or if they felt as uncomfortable with it as I did.
Goodreads says:
There was a terrible mistake - Wayside School was built with one classroom on top of another, thirty stories high (The builder said he was sorry.) Maybe that's why all kinds of funny things happened at Wayside-especially on the thirteenth floor.
