I created this activity as a center for my 5th grade team. It could also be used as a math task. Students are given 4 cards with fractions with unlike denominators on them. They have to find a common denominator then order them from least to greatest. They also have to draw a picture representation of each pizza. Once they are in order, they will know which table the leftovers belong to. There is also a second task in which students have to order the fractions from greatest to least.
