Grade 3-5-The striking photography in this book will not only whet an occasional appetite, but also satisfy the need for a visual treatment of the topic. Opposite three written representations of the same portion-a fraction, a decimal, and a percent-Thaler contributes clear, close-up illustrations. The large photographs framed in bands of bold color draw the eye from the matching numeral equivalents. While the examples include the tried-and-true pieces of pie and pizza and quarter of a dollar, Gifford relates more unusual divisions of a whole to illustrate other fractions: 1/7 of a week and 1/11 of a soccer team offer a fresh look at other portions. This simple text, paired with large vibrant art, provides a startlingly clear mathematical perspective.

Gr. 3-5. Notable for its clean design, this brightly illustrated book introduces the idea that fractions, decimals, and percents are different ways of saying the same thing. An introduction is followed by a picture of a single gym shoe and the explanatory words, "1/2 of a pair of shoes," ".50," and "50%." The next 14 double-page spreads follow the same pattern: a large, sharply defined photo and large-print text that defines the picture in terms of its subject along with three ways of expressing it numerically. But while "1/10 of your toes" (smartly illustrated with a big toe poking through the hole in a sock) is ".10" or "10%," some of the decimal numbers and percentages are rounded-off approximations: "1/7 of a week" is not exactly" .14" or "14%" of a week. If that's close enough for a teacher's purposes, then this attractive book will fit the bill. However, those who value the precision of mathematics will be disappointed that Gifford chose to use inexact equivalencies without at least mentioning the useful concepts of rounding and approximation. This is, nevertheless, a promising first book for Gifford, an elementary-school teacher, and another striking visual interpretation from Thaler, the photographer who illustrated George Levenson's Pumpkin Circle (2002).

Perhaps the low quality construction of this piece has me giving it a poor review. It has the feel of something printed at OfficeMax, more like a pamphlet than a book. Read morePublished on January 17, 2013 by B. Lee
This book has helped me in my classroom. The kids understand it more, because it deals with real, everyday things they are aware of.Published on December 30, 2012 by KK
This reminds me of a Tana Hoban book, and it's very clever. Visual learners and intuitive thinkers should get a lot out of it.Published on February 18, 2012 by J.A.
