I really want to start guided reading in my classroom. My class library is getting leveled as we speak. I just get confused about somethings with guided reading. How many times a week do you work with each group? I also know that you need to set up centers for the other groups to do while working with one particular group, but what do you do if one group finishes a center before another group? I really want to do guided reading and could use advice. Thanks!
