I'm ordering them right now. Do you have students even after you have explained centers a million jazillion times still ask. What are we supposed to do at center 1? Well problem SOLVED!! These are little speakers that you record the instructions on. Then when the students are at their center. They push the little button and it tells them what to do. WOW!!! Seriously this is going to make my life so-much-easier! They're on sale right now on Amazon. So go check them out.
