Abstract

Using an adaptation of the classic "locker problem" (Lenchner, 1983), we designed a series of spreadsheets with Microsoft Excel to engage pre-service middle-school and high-school math teachers in an activity related to basic concepts and terms in number theory. In this paper, we list the principles that guided our lesson design, present the problem, and discuss how solutions have led to a productive class discussion about prime and composite numbers, factors and factor trees, and square numbers and their recursive relationship.
