A bit irreverent yet, kind and truthful, this book is for substitutes, teachers, and administrators. It describes the work-life of an experienced substitute teacher through the lenses of "best practices." It begins with the need for education: Axiom (1) "Teaching is a prerequisite for human evolution" to Axiom (11) "Do not take anything personally", even when the students say you are "the best sub they ever had." For grades K-12, this book helps with classroom management techniques to keeping track of multiple assignments. All you need is a tolerance for ambiguity (everyday is different), a healthy lunch, and perhaps ear plugs for rainy day recesses. Author: Bill Buxton (MA, MBA, TESOL) has been a "mostly friendly" substitute for about five years for grades four through twelve in various socioeconomic districts. He believes the primary goal of a substitute teacher is to support the professional teacher by following the sub plans, with some discretion, of course.
