This is a powerpoint that can be used to keep students on the clock. It can be used for timing students for a variety of activities including snack time, independent work time, timed tests or any other activity that you would like to set a time limit that a visual aid would be helpful. I put it up on the smartboard for all students to see. The powerpoint counts down from 30 minutes all the way to "Times Up." It has a 2 minute warning as well to give students a heads up. It does not have to be set at 30 minutes, it can be set at any interval between 1 and 30 minutes and transitions slides each minute. I use this in my classroom and its a great time and classroom management technique and a handy visual for students to stay on task.
