Global Learner Project

So I am still delving into all this wonderful technology out there for my students and me. I am, as well as my whole team, actually making a commitment to using the Smart Board -so the ideas and collaboration are wonderful. I am still trying to manage the independent or small group usage of it and am thinking I am being too overprotective. Do any of you use it for centers? What are some strategies for making sure they are appropriate and safe without hovering? Maybe I am just a control freak? Thanks in advance.
