I am new to 1st grade this year. I was very nervous but found out I actually am loving it! We have done a lot of reviewing so far. I am going to be starting literacy centers soon--love that idea! I am very confused on how to run guided reading groups. I am planning on grouping the students by levels according to how they read. How do I meet the standards expected of me for each group if they are not at the same level? I plan to do literacy centers/guided reading for an hour, is that enough time? Should I do centers every day? Any ideas would be appreciated. Thanks for your help!
