Parent Testimonial: "We received the math book by Francis Sganga and my eighth grade son was so sad that he didn't get to use it as an introduction to those topics (we have 2 younger children and I often teach math at a local private school). He wants you to urge Mr. Sganga to write a similar book for high school students, preparing them for calculus. Thanks."

ABOUT THE AUTHOR

Francis (Frank) Sganga received his B.S. and M.A. degrees at the University of Florida
where, as a graduate student, he taught for two years. After working with the U.S. Corps of Engineers for two years, he succumbed to an urge to teach, and wound up spending six years
teaching at the high school level. Teachers salaries being what they were, and still are, he
decided his income was insufficient for a family of five, and moved into administration.
After three years, his superiors promoted him to the position of Mathematics Supervisor.

During his tenure as supervisor, he wrote two original competitive proposals for federal
grants (Success in Mathematics through Aural-Reading Techniques and Calculator-Assisted Mathematics for Every-day Living), that brought $1 million into the Volusia County, Florida school system. Both projects were validated by the U.S. Office of Education in Washington, D.C. for national dissemination.

In his supervisory role he spent a good deal of his time teaching gifted students at the
middle school level, as well as conducting in-service workshops for their teachers. He never allowed his penchant for teaching to lie fallow.

Also during that time he became the sole author of two major mathematics programs published by Charles E. Merrill (Bell & Howell) that were sold internationally with sales
topping $1.5 million, and invented 15 teaching aids (two patented in his name) that were
published and sold internationally by the St. Regis Paper Company.

Lastly, he wrote three articles for professional journals, which include A Bee on a Point, a Line and a Plane (NCTM's Mathematics Teacher), An Individualized Approach to Teaching Mathematics and How to Solve Word Problems, as well as six article related to education for
the local (New Smyrna Beach, Florida) newspaper, The Observer.

Currently, he is an Educational Consultant, and still tutors students from grades 4 through junior college. His current hobbies are writing, playing racquetball, and riding his 1100 cc
Honda Shadow motorcycle.
