Catheryne Draper has been learning from her students for over half a century of teaching, supervising the math program in a school district, advising math education at the state level, coaching math in schools, and presenting math workshops for teachers. She is the author of The Algebra Game, a hands-on multi-deck algebra program in four topics covering Linear Graphs, Quadratic Equations, Conic Sections, and Trig Functions that allows students to work together in cooperative groups, or individually, to identify the algebra relationships and patterns in the each topic. In addition to contributing many published articles, Draper is also the author of Winning the Math Homework Challenge: Insights for Parents To See Math Differently,User-Friendly Math for Parents: Learning and Understanding the Language of Numbers is Key, and How the Math Gets Done: Why Parents Don’t Need to Worry About New vs. Old Math.

About the Author

Spatial Sense Makes Math Sense makes math sound like fun, even though "math" and "fun" have been mutually exclusive categories for my entire life. I clearly recall my frustration as a child, attempting to master multiplication and not getting it. That experience left a life-long negative attitude about math and my ability to master it.

I dearly wish Cathy Draper, her skills, her passion, and her determination that all students love, value, and enjoy math, had been part of my math education! Buy this book for a child you love!

Cathy Draper’s passion to fight innumeracy is evident in Spatial Sense Makes Math Sense. The book is personable, conversational, and makes sense. It provides a great refresher of geometry and shows how parents can make sense of it to help their children. Each chapter is introduced with a quote that frames the theme of the passage and weaves history with foundational facts to make sense of mathematical theory. Draper has undertaken a remarkable goal by focusing on the support of parents to support the student learner.

Designed to help parents help their children with the content and psychology of math, this book focuses on visual models that support “Math Avoiders,” and can help them become "Math Aficionados." Catheryne Draper "has been learning from her students for more than half a century" and she shares wisdom and advice for families to rock math homework! The top to-dos include accepting mistakes, trusting your child, and being willing to learn along with them, rather than you learning it first.
