This paper describes a "learning community" designed for sophomore computer science majors who are simultaneously studying discrete mathematics. The learning community consists of three courses: Discrete Mathematics, Data Structures and an Integrative Seminar/Lab. The seminar functions as a link that integrates the two disciplines. Participation in the seminar enables students to study and appreciate the mutually beneficial relationship that exists between mathematics and computer science--a relationship that students often fail to see. Through carefully planned experimentation, students investigate how mathematics is used to formalize computer science, and how computer science can be used as a tool to explore mathematics.
