These cards can be used to show the center rotation for multiple groups. I put them into a pocket chart but they could be displayed on a bulletin board, magnetic board, ect. The chart is easy enough for my second graders to use and understand. The set includes 6 colors for groups (green, blue, red, yellow, purple and orange). It also includes the following center titles: Teacher Time, Word Word, Read to Self, Buddy Reading, Writing, ELA Games, Computer, Other, and a blank one so you can write in any center name you choose. I laminate all of the cards and write on the blank one with a dry erase marker.
