I need a secretary

So I have officially begun working on reading/literacy centers with my students. The first few days were a little chaotic (which is to be expected) but it is getting better. However, I need more time! What else is new? There is never enough time in the day, but with centers, students who do not finish with their work in that short 10 minutes are still way behind and everyone who can keep up is bored waiting for them to finish, which is exactly what I was trying to avoid. I don't think they are getting enough whole-group instruction now. Right now I have a group working on reading with me. I think I need to do more circulating because they are not quite advanced enough to actually read the directions and do the activity. grr. I also wish that I could get them away from the worksheets that go along with the curriculum, but still feel confident that they will succeed by the end of the week. Hmm...
