I had some readers in the past that had a hard time being motivated taking AR quizzes. I used this incentive chart which they LOVED!! I would write in the boxes a reward with a white "color switchers" marker. When they took an AR quiz they were able to take another color and color in the box. If an award magically appeared they received that award. Some of the awards I would write would be...piece of gum, pencil, lunch with teacher, bookmark, hug, high five. I KEPT SOME SPACES BLANK SO THEY DIDN'T KNOW IF THEY WOULD GET AN AWARD OR NOT. Sometimes they would color in he box and there would not be anything there.
