AUTHOR : Chris McMullen earned his Ph.D. in physics from Oklahoma State University and currently teaches physics at Northwestern State University of Louisiana. He developed the Improve Your Math Fluency series of workbooks to help students become more fluent in basic math skills. DESCRIPTION : This practice book is designed to help students develop proficiency in their arithmetic with negative numbers by offering ample practice. This book is conveniently divided up into four parts - one for addition, subtraction, multiplication, and division. In this way, students can focus on one arithmetic operation at a time. EXAMPLES : Each part begins with a concise set of instructions and a couple of examples to serve as a guide. ANSWERS : Answers to exercises are tabulated at the back of the book. This helps students develop confidence and ensures that students practice correct techniques, rather than practice making mistakes. PHOTOCOPIES : The copyright notice permits parents/teachers who purchase one copy or borrow one copy from a library to make photocopies for their own children/students only. This is very convenient if you have multiple children/students or if a child/student needs additional practice. INTRODUCTION : An introduction describes how parents and teachers can help students make the most of this workbook. Students are encouraged to time and score each page. In this way, they can try to have fun improving on their records, which can help lend them confidence in their math skills. THE IMPROVE YOUR MATH FLUENCY SERIES OF WORKBOOKS Chris McMullen, Ph.D. This series of math workbooks is geared toward practicing essential math skills. As a physics teacher, Dr. McMullen observed that many students lack fluency in fundamental math skills. In an effort to help students of all ages and levels master basic math skills, he published this series of math workbooks on arithmetic, fractions, algebra, trigonometry, and more.
