Read Danica McKellar's posts on the Penguin Blog. The "New York Times" bestseller-from the author of "Math Doesn't Suck "and "Hot X: Algebra Exposed"-teaches girls how to kick pre-algebra butt In her "New York Times" bestselling books, actress and math genius Danica McKellar shatters the "math nerd" stereotype and gives girls the tools to ace middle-school math in her unique, just- us-girls style. Now, in her second book, "Kiss My Math," McKellar empowers a new crop of girls-seventh to ninth graders-to tackle the next level of mathematics: pre-algebra. Stepping up not only the math but the sass and style, McKellar helps math-phobic teenagers moving up into high school chill out and finally "get" negative numbers, variables, absolute values, exponents, and more. As she did so effectively in "Math Doesn't Suck," McKellar uses personality quizzes, reader polls, real-life testimonials, and stories from her own life-in addition to clear instruction, helpful tips, and practice problems-revealing why pre-algebra is easier, more relevant, and more glamorous than girls think. McKellar is clearly reaching her audience: parents, teachers, and especially girls are asking for more.
