Larry Gonick is a former Harvard instructor. He offers a series of Cartoon Guide about Mathematics. His books remind me of the funny and informative posters that I saw in my high school math classroom. However, this book contains way more information about high school math: algebra. The key idea of this book is to teach algebra textbooks but with a lot of engaging and humor visual aids. Larry covers the algebra essential including linear equations, polynomials, quadratic equations, and graphing techniques. The cartoons play three roles: support the reader to have a better understanding of the topic, demonstrates the key concept of the unit, and defined the rationale of the content. The book contains about half of the word and half of the cartoon. Algebra is threatened by high school students and teachers. By adding visual images to the books, algebra can be engaging and lively humor. Outside of the content of this book, this teaches us the power of the graphic novel. The cartoon can be used not only for entertainment but also to learn from.
