When I taught kindergarten I used this everyday during center time. I had 12 centers and 27 students. So I numbered each center in the classroom and put each students name under the center that they were to start at. The slides automatically rotate every ten minutes. They will automatically be sent to the next center.
The PowerPoint also makes a nice ding sound when it is time to clean up. Then it counts down thirty seconds with a visual timer, then sends students to their next center.
You can also replace the center numbers with center photos.
Copy a students name and press CONTROL F, hit replace, then replace with your students name.
