When beleaguered Babymouse received an F minus on a math quiz, her teacher is willing to forgive the grade IF she will join the Fighting Fractions, the school’s math Olympics team. “Look on the bright side, Babymouse—you may be missing lunch, but at least you get to do math!” Babymouse is definitely the weak link in the Fighting Fractions chain, at least when it comes to math skills, but as the big competition against the rival Owlgorithms approaches, she conjures a vivid fantasy in which she and her fellow teammates—the “Fellowship of the Slide Rule”—embark on a quest. The competition itself plays out in Babymouse’s mind as a jousting tournament in a winning graphic novel full of references to well-known books and movies and an abundance of math puns. And of course, there is the inimitable Babymouse, in all her black, white, and pink graphic-novel glory, who emerges triumphant when imagination turns out to be just what she needed to understand math.
