This article describes how to build a classroom community by building representations and visualizations of data related to students' names. The goal of this task was to allow students to get to know each other's identities better by collecting and analyzing data about their names and exploring the connection between names and identities. The task served as a "mirror" and "window" (Bishop, 1990) for students that allowed them to see themselves reflected in the math and to learn about other cultures (such as Korean culture in this case) outside of their classroom.
