This is a slideshow I prepared for my Literacy Centers this year. I teach Second grade so I have found that something simple and visual is the way to go. The slideshow is set up for Literacy but can be easily edited to suit any subject, or the way you organize your differentiated instruction groups.
The slide includes:
Having a visual way to remind students (and myself) where everyone needs to be at all times has greatly reduced the number of interruptions I receive during my differentiated instruction time. Also, it has helped the transition time between center groups as well. As soon as I switch to the clean up slide, the students start singing that it's time to clean up. Soon after, I call a countdown and when I hit 1, every student points to their next center.
Finally, I call out "Switch!", and as they quickly and quietly move to their next center and get to work, I click to the next slide, and pull my next small group.
I hope this could become a resource for you like it became for me!
