Eye training. Clump counting. Box and count. Bruce Goldstone offers strategies and examples of how to estimate in this numerically challenging follow-up to Great Estimations (Henry Holt, 2006). As in his original volume on how to strategically guess at the number of objects in a group, Goldstone uses eye-catching photographs of items to be estimated, from the number of rubber ducks in arrangements growing larger on successive pages to the number of seeds on a dandelion, and much more. He also includes estimation exercises on how to figure height, weight, size, and volume. Each page’s puzzler includes a hint on the strategy to use in a book that offers skill-building and opportunities for practice that can be easily extended beyond the page. (Ages 7–11)
