Very little background in abstract algebra is needed for a course based on this primer. The content and methodology has been implemented successfully for well over a decade with in-service secondary teachers seeking licensure or an MA degree in teaching mathematics. The oft-quoted maxim -"You learn mathematics by doing mathematics" is embraced.

A valuable by-product: A significant number of teachers who have experienced this material have incorporated a variety of the topics and problems into their secondary curriculum as they encounter topics like closure, binary operations, modular
arithmetic, the structure of the integers (yes, gcd and lcm play a role), and the rational and real numbers.
