I'm switching to upper grade next year at a new school and a brand new position/classroom. I'm working on making a classroom library (which you all have already been so helpful with!) I was wondering what types of books are popular now for grades 3-5? Any series that I need to be sure I get? (like Diary of a Whimpy Kid or something). If I am going to spend my own money on books, I want to make sure I get books the kids with want to read :lol: Thank you!!
