How Tall, How Short, How Faraway?

Book excerpt: If you think a yard is a place to play ball, feet are only good for wearing shoes, and a palm is just a tree that grows in Miami, think again! They are all actually units of measure--different ways of measuring how tall, how short and how faraway things are. In this simple, hands-on math concept book, you'll learn how the ancient Egyptians and Romans used their fingers, hands, arms, and legs as measuring tools. But don't worry if it's all Greek to you. With David A. Adler's playful, informative text and Nancy Tobin's colorful illustrations explaining the difference between customary and metric systems, you'll really measure up!
