Reviews

Gr 2-5-Pretzels, cheese slices, and bread, as well as paper and pencil are used here to teach math concepts. Adler's simple, to-the-point explanations and Tobin's bright, colorful cartoon drawings work well together to bring basic geometry to primary-grade students. The different print sizes and bright colors create a bold visual effect. The book concludes with a one-page list that defines the shapes and angles examined. Although the use of food products to illustrate these concepts is common at the preschool and primary level, many adults have reservations about this practice. Nevertheless, this is a bouncy, hands-on introduction.-Eunice Weech, M. L. King Elementary School, Urbana, IL
