Discrete mathematics, the mathematics of decision making for finite settings, is a topic of great interest in mathematics education at all levels. Attention is being focused on resolving the diversity of opinion concerning the exact nature of the subject, what content the curriculum should contain, who should study that material, and how that material should be taught in the classroom. This document details a set of recommendations on the infusion of topics from discrete mathematics into the secondary school (grades 7-12) mathematics curriculum. The suggestions are accompanied by a list of resources, including software, which will aid in the development of specific topics. Modeling, use of technology, algorithmic thinking, recursive thinking, decision making, and mathematical induction as a way of knowing are six unifying themes that emerge when discrete mathematics is studied and applied. Recommended topics for emphasis in discrete mathematics before algebra, with algebra, and with geometry are included. Appended is an outline for a semester course in discrete mathematics. (KR)
