I am going to be teaching ela next fall and I'm trying to start planning now. I'd like to organize it like I organize my math where most of the time we do a 90 min block with 3 30 min rotations. I'm thinking that I could work with a small group each rotation, and have the second group do silent reading, and the third group do a center. Does that sound ok? Any suggestions? I'm wondering what kind of centers I can design, however, that a group can work on for up to 30 min..... Thoughts?
