Great Estimations

32 pp. | Holt | September, 2006 | Trade ISBN 0-8050-7446-5 $16.95
(3) 4-6 This well-conceived introduction to visual estimation starts off with a colorful photo chock-full of sets of tens--ten toy cars, ten pretzels, ten dominoes, etc.--to help readers get a mental picture of what ten looks like. This "eyeball practice" continues with collections of hundreds and thousands before readers learn and try out two different estimation strategies.
