This powerpoint is for any classroom and any grade. The PowerPoint is a timer set to change slides every minute. If you want your students to work for only 10 minutes, set the timer to 10 minutes and click start. The PowerPoint counts down every minute until the 10 minutes are up. No one has to ask you, how many minutes are left.
