I am switching from Head Start to second grade this next year. I moved all the stuff from my Head Start room to my second grade room the other day. I started moving furniture around and stuff and realized... I don't know what to do with my room. I mean, I have my desk where I want it, computers, and once cabinet, but what else? I don't know what kind of centers to use in second grade, and where tables and bookshelves will go for that... any insights?
