I am moving down to 3rd from 4th. I have a large library modeled after Beth Newingham. I didn't have picture books last year but plan to add them this year. I am not sure about categories though. Can anyone tell me what they use? I have quite a few Berenstain Bears and Arthur so I can make labels for those. Clifford, Eric Carle, etc should I not bother bringing in because they are too young? I expect to have a few reading at first grade level so that would be Clifford, etc... I also have a bunch of Step Up Readers, etc. We use Accelerated Reader so I was wondering if I should do the obvious series like Arthur but then do a lot by reading level? I know the primary grades have tubs that say 1.0-1.5 etc. I'd love to hear/see what others do. Thanks!
