My dad and I had some tough times as I was growing up, but I remember with a golden glow the spring when I was in the 8th grade. My dad had a heart attack and in those days the recovery included a long period of restricted activity, so he would be reading in the living room when I got home from school. He was a reserved man and I think it was hard for him to be very demonstrative, but we could connect over my math homework. That spring we did my math homework together almost every day. I loved the attention and I am sure those afternoons had something to do with my becoming a math major a few years later when I got to college.

As parents we value precious moments of connection and communication with our children. Spending time with our children on their homework in the right emotional atmosphere can strengthen the bond with them and lay a foundation for a love of Book 2 learning that will last a lifetime.

Through the years as we have worked in the field of math education and written math materials, a frequent question from parents has been, "Why don't you write a book for us so we can help our kids do their homework?" Also, friends and family have occasionally asked us for help with their children's math homework. The puzzled parent was usually faced with a worksheet and a student who seemed to have no idea about how to do the problems. The worksheet would have no teaching section, review material, or worked examples. The person trying to help with the homework would be at a loss about how to help. Often all that was needed was a refresher of the math skills involved. Over time it occurred to us that a written resource with some worked-out examples would be very helpful to moms, dads, grandparents, aunts, uncles, caregivers, babysitters, or anyone else who might be having problems helping with homework.

How the Modules Are Organized

This book is made up of self-contained lessons, which we call modules, that present many of the common arithmetic concepts taught in primary and middle school. We assume that you remember the basic whole-number arithmetic skills: addition, subtraction, multiplication, and division. The concepts we cover in detail are sets, numbers, fractions, decimals, ratio, proportion, percents, and problem-solving skills. In each module, we point out why the topic is important, present the definitions, and give examples. The examples are worked out in a step-by-step format, allowing you to review the skills needed to solve. We give you tips and hints and refer you to other modules to review prerequisite skills. Next, we include a few problems so you may test your understanding of the concepts in the module or work some problems with your child. We provide complete solutions for you. Finally, we provide a short and fun activity for you to do with your child to practice the concepts of the module.
