Everything You Need to Ace Math . . . covers everything to get a student over any math hump: fractions, decimals, and how to multiply and divide them; ratios, proportions, and percentages; geometry; statistics and probability; expressions and equations; and the coordinate plane and functions. The BIG FAT NOTEBOOK™ series is built on a simple and irresistible conceit-borrowing the notes from the smartest kid in class. There are five books in all, and each is the only book you need for each main subject taught in middle school: Math, Science, American History, English Language Arts, and World History. Inside the reader will find every subject's key concepts, easily digested and summarized: Critical ideas highlighted in neon colors. Definitions explained. Doodles that illuminate tricky concepts in marker. Mnemonics for memorable shortcuts. And quizzes to recap it all. The BIG FAT NOTEBOOKS meet Common Core State Standards, Next Generation Science Standards, and state history standards, and are vetted by National and State Teacher of the Year Award-winning teachers. They make learning fun and are the perfect next step for every kid who grew up on Brain Quest. Workman Publishing is a New York-based publisher of award-winning nonfiction for adults and children. Hi! These are the notes from my world history class. Oh, who am I? Well, some people said I was the smartest kid in class. I wrote everything you need to ace MATH, from the FRACTIONS to the COORDINATE PLANE, and only the really important stuff in between-you know, the stuff that's usually on the test! I tried to keep everything organized, so I almost always: - Highlight vocabulary words in YELLOW - Color in definitions in green highlighter - Use BLUE PEN for important people, places, dates, and terms - Doodle a pretty sweet pie chart and whatnot to visually show the big ideas If you're not loving your textbook and you're not so great at taking notes in class, this notebook will help. It hits all the major points. (But if your teacher spends a whole class talking about something that's not covered, go ahead and write that down for yourself.) Now that I've aced math, this notebook is YOURS. I'm done with it, so this notebook's purpose in life is to help YOU learn and remember just what you need to ace YOUR math class.
