Nag, nag, nag...Sometimes teachers find their voices tired from asking the students to be quiet and sit down. This tool although simple has worked wonders in the primary grade classrooms. It has three simple colors each attached with a sound. You can morph the consequence how you need to, for me it was taking away marbles from the jar. I highly suggest using a wireless mouse so that you can move around the room and not be tied to the computer to have to push it. Just make sure the speakers are plugged in.
