Mathematics— Irving Adler
Published by Bantam Doubleday Dell/Random House, 1990. Did you know that six is a perfect number? A number is called perfect if the sum of its divisors equals the number. One plus two plus three equals six, so six is a perfect number. This book uses text, illustrations, charts, and simple computer programs to explain natural, prime, and triangular numbers. Polygons and angles are also explained. |

Sideways Arithmetic from Wayside School— Louis Sachar
Published by Scholastic, 1992. How much is "he plus me?" What do you get when you subtract "pop from yoyo?" One of the students at the Wayside School, Sue, can't figure it out.

Math-terpieces: The Art of Problem Solving— Greg Tang
Published by Scholastic, 2003. If you think you can't learn math and art history at the same time, think again. This innovative approach to grouping, addition, and problem solving also exposes the reader to impressionism, cubism, and surrealism, as well as many other periods of art. Each colorful double-page spread introduces a fun poem, a painting, and a problem. For example, Van Gogh's "The Starry Night" is paired with a lighthearted verse: "See the nighttime all aglow? It's the vision of van Gogh . . ." Then a problem is posed: "Can you group the stars in heaven? Find four ways to make a seven!" The colorful swirling stars on the opposing page provide a grouping challenge for the reader. Clear explanations of the solutions to the puzzles are provided at the end, as well as some art history notes for the reader intrigued by the paintings. From Degas's ballerinas to Andy Warhol's soup cans, this is a beautiful way to learn about math. |
