A good way to organize centers and to help your kids know what they need to do is to place all of your center materials in boxes. Plastic stackable boxes with lids work well. Make pictures to go along with each center, such as a picture of a calculator or ruler for math, a picture of a book for reading, and so on. Tape these pictures onto the corresponding boxes so that they are easily visible and recognizable by students. Have a center checklist for each student at the beginning of centers for each week that contains the same images used on the Center Boxes. Students will know when they are done with their center work or what they still need to complete by checking off (or coloring in) the pictures on their checklist. This will help your students to become independent workers; this gives you more time to teach!
