Editorial Reviews

Children's Literature
Some mathematical concepts are hard to grasp. Elementary school teacher and author Scott Gifford admits he too, at a younger age, "was flummoxed by fractions, daunted by decimals, and puzzled by percents." In the full page introduction, piece, part, and portion are discussed as similar but different concepts. "Hello Hola Bonjour" are the friendly greetings the introduction uses to welcome us...a similar concept expressed in three different ways. In the rest of the 32 pages, each two-page spread illustrates the concepts in four different ways. One of my favorites is a full page picture of two feet with red socks. The left big toe is sticking out of a hole in its sock. On the neighboring page we see: "1/10 of your toes .10 10%." Other images that kids can relate to include one gym shoe, one piece of pie in its tin, one whole pizza, one egg sitting in its carton, and one soccer player wearing a jersey surrounded by ten more jerseys. This book reinforces that age-old formula: 1 picture = 1,000 words. 2003, Tricycle Press, Ages 7 to 10.

Gr 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.-Mary Elam, Forman Elementary School, Plano, TX Copyright 2003 Reed Business Information.
Kirkus Reviews
Math classes in the upper elementary grades and middle school are the logical audience for this deceptively simple work that shows the correlation between numerical amounts expressed as fractions, decimals, and percentages. Each left-hand page uses the repeating pattern of a fraction, a few descriptive words in colored type, and then the corresponding decimal and percentage. Right-hand pages show an attractive photograph of the object under discussion against bright borders. Some of the examples are easy to comprehend (3/4 of a sandwich, .75, and 75%) and others are more complex (1/12 of a dozen eggs, .08, and 8%). A juicy piece of pizza on the front cover is complemented by the rest of the pizza on the back cover, and the concept of a whole (1 whole pizza, 1.00, 100%) is the concluding spread. This clever idea will work best when introduced to students by a mathematically literate adult. (author’s note) (Picture book/nonfiction. 8-13)
