This product can be used in a variety of ways. I write my student numbers or names in the large bubbles using a dry erase marker. Then I attach the small bubbles to clothespins and write the center name on it. Each day I move the clothes pin so each group rotates to a new center. I also included a blank circle for you to write your own center. Names or
numbers can also be written on small bubbles and center names written in large bubbles.
