Being Quiet at Appropriate Times

Our class is a very creative and expressive group! I really appreciate this about them, however we need to work on being quiet during appropriate times. It is important to talk and communicate with one another, however I would like the students to talk softly during circle, seat, and center time. It becomes difficult to work with my reading groups when the students talk loudly during this time. Let's work together to improve our noise level during circle, seat, and center time. Thank you!!!!!!!
