Greater Estimations
Grade 2–5—Goldstone builds on the topics introduced inGreat Estimations(Holt, 2006) and also discusses how to estimate length, weight, area, and volume. He does an exceptional job of breaking down the process of so that even early elementary students can comprehend it. The author also effectively introduces different methods of estimation, including the "box and count" technique and clump counting. The vivid, eye-catching photographs are the highlight of the book. Each page or spread features a simple question in large, bold text, followed by a short explanation of how to achieve the answer. Hint boxes appear on almost every page. Speech bubbles emanate from critters throughout the book, adding a humorous touch. An author's note provides information on how adults use estimations as a part of their everyday lives. With an appealing layout that lends itself equally well to browsing or curriculum support, this lively book would be an excellent addition.—Maren Ostergard, King County Library System, Issaquah, WACopyright © Reed Business Information, a division of Reed Elsevier Inc.
