About the Author

Susan Greenwald, M.A. Ed., has degrees in special education from the University of Arizona and Arizona State University. She is an educator with many years of successful teaching experience and has written five books directed at helping children master math facts and other mathematics skills. Greenwald believes that after demonstrating understanding of computation, every student should be taught a way to memorize the math facts. This will allow them to succeed in higher-level math without having to count on fingers or use number lines or charts to get answers. Her latest book, Ten Divided by Five Is Not Five: Using Multiplication to Make Division Easy is now available in many educational and bookstores around the U.S.!
Addition and Subtraction: Beyond Math Facts  was published by Longevity Publishing in 2012 and was designed to help any age student master addition and subtraction with and without regrouping. Her previous books, Two Plus Two Is Not Five: Easy Methods to Learn Addition and Subtraction and Five Times Five Is Not Ten: Make Multiplication Easy were published in 2006 and 2008 respectively. In 2006, Two Plus Two Is Not Five won First Place in the Workbook category of the Evvy Book Awards. Five Times Five Is Not Ten was listed in Resources for Successful Teaching in the January 2009 issue of Learning Magazine and was an Award-Winning Finalist in the Children’s Educational category of the USA Book NewsNational Best Books 2008 Awards. Greenwald’s first book, How to Teach Math Facts, is published by Teacher Created Resources.

Greenwald taught special education in both private and public schools including the Cherry Creek School District in Colorado and the Paradise Valley School District in Arizona. Through her private practice, she has worked with elementary and middle school students of all levels and abilities. The methods, strategies, and worksheets in her books developed from a need to help her own students succeed in math.

Greenwald presented at the 2006 Conference for Advancement of Mathematics Teaching in Houston, TX; the 2007 Annual Conference of the Arizona Association of Teachers of Mathematics; the 2007 to 2009, 2011 and 2013 conferences of the Colorado Council of Teachers of Mathematics conferences; and the 2006 to 2009 California Mathematics Conferences in Pacific Grove, CA.

The author resides with her husband in Colorado where she continues to develop quality resources to help children succeed in school. She has three adult children who mastered math facts at a very early age and three young granddaughters who will “know” their math facts when they enter school!

I have a 9 year-old daughter going through the multiplication book like a champ, and ditto on my 6 year-old son with the addition book!  I assign them one page a day in addition to their math curriculum and it's working perfectly. Couldn’t be more pleased!
