Abstract | "Who has been to Dairy Queen® and purchased a Blizzard?®" Ms. Bosetti asked her students. During the summer, Bosetti had seen many of her former and future students at the local Dairy Queen enjoying Blizzard desserts and wondered, "Which Blizzard size is the best value?" She used this context for a ratios and proportions task to give students experience modeling with mathematics. Modeling with mathematics requires engagement in problem solving that is focused on realistic situations. This characterization of modeling with mathematics brings up two key instructional questions: What should students engaged in modeling with mathematics be doing? What should teachers do to promote modeling with mathematics? This article describes a mathematical lesson in which the students are to determine which size Blizzard is the best value using a graphical approach, a pictorial approach, and a tabular approach.
