I would like to dedicate this book to my son, Noah Hanks, who was in a 7th grade math class while I wrote this book. He was an invaluable source of inspiration and motivation and kept me focused on the concepts you really must know. Thank you for your patience and your help. I would also like to thank Garret Lemoi for supporting me and my writing. I look forward to many more years of working with you.

W elcome to your new math book! Let us try to explain why we believe youve made the right choice. Youve probably had your fill of books asking you to memorize lots of terms (such as in school). This book isnt going to do thatalthough youre welcome to memorize anything you take an interest in. You may also have found that a lot of books make a lot of promises about all the things youll be able to accomplish by the time you reach the end of a given chapter. In the process, those books can make you feel as though you missed out on the building blocks that you actually need to master those goals.

With Must Know Math Grade 7, weve taken a different approach. When you start a new chapter, right off the bat you will immediately see one or more must know ideas. These are the essential concepts behind what you are going to study, and they will form the foundation of what you will learn throughout the chapter. With these must know ideas, you will have what you need to hold it together as you study, and they will be your guide as you make your way through each chapter.

To build on this foundation, you will find easy-to-follow discussions of the topic at hand, accompanied by comprehensive examples that show you how to apply what youre learning to solving typical 7th-grade math questions. Each chapter ends with review questions350+ throughout the bookdesigned to instill confidence as you practice your new skills.

This book has other features that will help you on this math journey of yours. It has a number of sidebars that will either provide helpful information or just serve as a quick break from your studies. The sidebars (by the way) point out important information, as well as tell you what to be careful about math-wise. Every once in a while, an sidebar (in real life) will tell you what youre studying has to do with the real world; other IRLs may just be interesting factoids.

In addition, this book is accompanied by a flashcard app that will give you the ability to test yourself at any time. The app includes 100-plus flashcards with a review question on one side and the answer on the other. You can either work through the flashcards by themselves or use them alongside the book. To find out where to get the app and how to use it, go to the next section, The Flashcard App.

We also wanted to introduce you to your guide throughout this book. Weve had the pleasure of working on a number of projects with Wendy Hanks but are glad to, finally, have the opportunity to work with her on a project starting from scratch. Wendy has a clear idea what you should get out of a math class in 7th grade and has developed strategies to help you get there. She also understands the kinds of pitfalls that students can fall into and will help you solve those difficulties. In this book, Wendy applies that experience both to showing you the most effective way to learn a given concept and how to extricate yourself from any trouble you may have gotten into. She will be a trustworthy guide as you expand your math knowledge and develop new skills.

Before we leave you to Wendys sure-footed guidance, let us give you one piece of advice. While we know that saying something is the worst is a clich, if anything is the worst in the math youll cover in 7th grade, it could be algebraic equations. Let the author introduce you to equations and show you how to work confidently with them. Take our word for it: learning how to handle algebraic equations will leave you in good stead for the rest of your math careerand in the real world, too.
