This is a very easy, intuitive activity for students to use to explore mean, median, and mode. All you need to do is have them list their shoe sizes first. (They prefer to do this anonymously in middle school.) Then I pair them up and they complete the activity. This could be used as a formative assessment / performance task for the common core. It also can lead to a class discussion about appropriate measures and outliers. Could be used to generate graphs as well.
