This includes a class set of 21 questions from a set of 7. The questions can be differentiated based on the level of students current understanding. I created and used this for 5th graders. This math lesson focuses on adding fractions with unlike denominators. The students really loved it. All of the fractions equal one whole Hershey's Bar.
