I have tried centers every year, I think this is my lucky year.... I teach 3rd grade. I don't know how many kids I'm going to have, but we have 90 minutes of reading. I think I'd do centers a few times a week....I'm not sure. I was going to do a reading group with me, a spelling center, a computer center, and maybe a silent reading center (then they'll have to journal about what they read about). Does anyone else have ideas???
