This real life problem presents itself as a riddle for students to figure out what fraction of a pizza four different friends ate. Students need to use their knowledge of comparing fractions and equivalent fractions in order to figure out what each child ate. They're given clues like "Toby ate more than anyone else," and they have to come up with a model to represent what each child ate. There are multiple ways to solve this and different possible answers, so it is considered an "open ended" question.
After solving students are given 3 questions to reflect on what they did and help them make connections to how this solving this problem has enhanced their knowledge of fractions.
