Light a fire under your young mathematician! In The Golden Rectangle, author Gillian Neimark tells the tale of a 10-year-old girl from Puddleville, Georgia, who wants to grow up to be a horse rustler (although she’s not sure exactly what that is). Unfortunately, her destiny may lie elsewhere. After finding a mysterious key in her secret hayloft hideout, Lucy Moon is visited by Square Man, a 4-inch, square–shaped wizard intent on removing all curved lines from the world. Square Man tries to convince Lucy that an evil wizard named Dr. Pi is trying to make spirals out of all of the rectangles in the world. Lucy is skeptical and uses what turns out to be her magic key to land in the closet of Flor Bernoulli, herself a magical 10-year-old in New York. The girls embark on a whimsical adventure as they try to prevent Square Man from “squaring” the earth. The story is light and fun while introducing the reader to the concept of the Golden Rectangle (a mathematical term referring to a rectangle with a specific ratio of dimensions which is considered to be the most aesthetically pleasing of all rectangles. It has some other nifty properties as well). This is a sequel to The Secret Spiral, by the same author.
The Number Devil: A Mathematical Adventure, by Hans Magnus Enzensberger, takes a more direct approach in teaching mathematical concepts. Robert, the main character, hates math. The Number Devil takes over his dreams to teach him mathematical concepts in his sleep, one concept a night for twelve nights. Using everyday language and very few technical terms, The Number Devil brings clarity to topics such as infinite numbers, prime numbers, and Fibonacci numbers. Using pictures, diagrams and clear examples, the Number Devil helps Robert understand the topics and shows shortcuts to quickly showcase the principles. Even readers with a mild case of arithmophobia will learn to appreciate math after reading these titles.
