10,000 Subtraction Problems Practice Workbook

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.

CONTENTS This practice book is designed to help students develop proficiency with their subtraction skills by offering ample practice. This book is conveniently divided up into five parts:

• Part 1 reviews subtraction facts with single-digit minuend and difference since swift knowledge of these is critical toward subtraction mastery.
• Part 2 is limited to two-digit numbers minus one-digit numbers. This way students are not challenged with too much too soon.
• Part 3 focuses on two-digit minus two-digit subtraction.
• Part 4 involves three-digit numbers.
• Part 5 features a variety of multi-digit subtraction problems.
• An introduction describes how parents and teachers can help students make the most of this workbook.
• An addition table is provided to help students who are just learning their subtraction facts.

PRACTICE This is a practice workbook geared toward practicing problem-solving skills. As such, it consists of worksheets with practice problems in the spirit of old-fashioned practice sheets. This is suitable for students who need to practice basic skills, and is effective for many students. It is not one of the modern math textbooks that are designed to entertain bored students.

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.

Chris McMullen is a physics instructor at Northwestern State University of Louisiana. He earned his Ph.D. in phenomenological high-energy physics (particle physics) from Oklahoma State University in 2002. Originally from California, he earned his Master’s degree from California State University, Northridge, where his thesis was in the field of electron spin resonance. 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 has published this Improve Your Math Fluency Series of math workbooks on arithmetic, fractions, and algebra.
