Overview
How tall is your best friend? How short is your little brother? How faraway is your school? Do you know how to measure distance, height, and length? Ancient Egyptians and Romans used their fingers, hands, arms, and legs as measuring tools. But you won't have to become a human ruler if you understand terms such as meter, mile, and yard. This third math concept book from the team of David A. Adler and Nancy Tobin uses simple text and bold, graphic art to explain the different systems of measuring, and helps you decide which ones are best for certain situations. Once you learn these basic concepts, you'll really measure up!Introduces several measuring systems such as the Egyptian system, the inch-pound system, and the metric system.

The author and illustrator of two previous math books (Shape Up! and Fraction Fun) team up again to present methods of measuring in their hands-on, let's-have-fun style. They begin by offering practical ways for readers to apply the measuring units of ancient Egypt (digit, palm, span, cubit) in order to demonstrate the importance of a standard unit of measure ("If everyone used her arm to measure, we wouldn't know the exact size of anything!"). From there they introduce the two contemporary systems of measurement-customary (inch-pound) and metric-with brief explanations of how these systems were derived. Readers can then follow instructions to make a ruler that measures inches on one side and centimeters on the other. They will also learn the difference between kilometers and miles, and that a speedometer and odometer are tools for measuring distance. While Tobin's cartoonishly offbeat illustrations radiate enough pizzazz to motivate even the most resigned math haters, she fails to create a consistent scale for illustrated units of measurement. Small units, such as the digit and inch, are drawn to life, while larger units such as the palm and foot are scaled down (on the same page) without explanation, a choice which may confuse (or provoke!) those who have their home-made rulers at the ready. -- Horn Book Magazine
