Hershey Fraction Fun

As a culminating activity to our fraction unit, we read the Hershey Fraction book and each student received their very own chocolate bar.  We divided it into 12 equal parts.  The students first got to eat 1/12 of their bar.  We moved to 2/11 then 3/9.  Once they had eaten half of their bar we divided the 6 pieces in 3 equal groups and they were told to eat 1/3.  They were reducing fractions and didn't even realize it.  It was so much fun.  Some students couldn't even finish their chocolate bar.  They had trouble eating 12/12 or 1 whole!
