This book is the third in the series about Wayside School. Wayside School is a strange school that is 30 stories tall. The classroom at the very top, room 30, is the focus of the stories. The book is basically a compilation of short stories about the students in room 30 and the events that take place involving room 30. I believe this book is a nice addition to the classroom library I am creating. I love Louis Sachar, so I will be collecting quite a few of his books.
