What’s nice about the wireless device is that not only can the teacher be anywhere in the class, but the projecting iPad can also be given to a student to share their work as well. Or...you can just connect the WiPad to a student device.
Unlike an interactive whiteboard that requires training, keeps you tethered to the front of the room, and costs thousands, consider a WiPad Pro. It works on an iPad 2 or 3 and runs for $299.
