Editorial Reviews

From School Library Journal

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.

From Booklist

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).

Format: Paperback
Has pictures of "fractions" that kids are familiar with, such as 1/2 of a pair of shoes, 1/7 of a week, 1/3 of a traffic light.
It is laid out with the picture on the right hand page, and on the left hand page nice and big, the fraction on top (1/6), the words in the middle (of a six-pack), and on the bottom both the decimal (.166) and the percent (16.6%)

So here comes my question about this book... wouldn't you round the repeating .166666 up to .167 or put a line over the 6 to show it's repeating ? (I'm no math authority, but that's the way I understand it.) That's o.k., my son has fun finding "mistakes" and figuring out what it "should be," which is a teaching opportunity in itself.

I found this book more useful as reinforcement and review once I had already introduced my son to fractions, percents and decimals, and their relationship to each other. Otherwise, a kid may see the logical connection to 3/4 of a sandwich and the fraction, but be confused by the decimals and percents. Of course, that can be an opportunity to explain how they are related. :) But the explaining will be up to you... that's not covered in this book. It's more of a visual-aid teaching tool. I was a bit disappointed when I first got it at how simple it was, but It really is handy to have something like this to use.

The premise of the book is excellent. Unfortunately the careless execution and sloppy arithmetic render the book unusable. It is alarming that teachers have given high ratings to this book. One-twelfth is not equal to 8%. There are several similar errors that are completely unnecessary. Why did the author not choose everyday items that can be expressed as fractions and their whole number percentage equivalents?

This is a great resource for teachers to use to introduce the fractions, decimals, and percents to their classes. It really can be used in any early elementary grade. It has mostly photos with hardly any written parts but it is a very useful resource!

I continually use this pictorial book to help familiarize students with fractions. The graphic representations and supportive numerical information (expressed as fraction, decimal, & percentage,) on the reverse of each graphic are very valuable. Extremely useful and USER-FRIENDLY teaching tool! Many thanks.

I read Piece = Part = Portion. I am in third grade. I think this book would be good for first graders because there are about 3-5 words on each page. This book is about fractions, decimals, and percents and comparing them with every day objects.
