Just as hola and bonjour express "hello" in different ways, fractions, decimals, and percents describe the same quantities in different ways. While it may sound simple, this basic math concept often baffles children. The straightforward text and photographic examples from everyday life in PIECE=PART=PORTION are a terrific boon to elementary school math students everywhere.

SCOTT GIFFORD is an elementary school math teacher who lives in Sebastopol, California.

Award-winning photographer SHMUEL THALER works for the County Sentinel in Santa Cruz, California, where he lives with his wife and two daughters.

"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."
