This book is a collection of articles by experienced educators and explains why and how discrete mathematics should be taught in K-12 classrooms. It includes evidence for "why" and practical guidance for "how" and also discusses how discrete mathematics can be used as a vehicle for achieving the broader goals of the major effort now underway to improve mathematics education. This volume was developed from a conference that took place at Rutgers University entitled "Discrete Mathematics in the Schools: How Do We Make an Impact?". Chapters include: (1) "Discrete Mathematics in the Schools: An Opportunity To Revitalize School Mathematics" (Joseph G. Rosenstein); (2) "The Impact of Discrete Mathematics in My Classroom" (Patrick Carney); (3) "Three for the Money: An Hour in the Classroom (Nancy Casey); (4) "Fibonacci Reflections--It's Elementary!"
