The "Looking at Animal Parts" series of library bound books is a level one reader that supports standards of learning for life science. It is ideal for early readers as well as very young children. Word repetition facilitates learning new words and building vocabulary. The photographs and formatting enhance the value of these books. The large, colorful photographs clearly illustrate the topic at hand, supporting the text. Large letters, ample spacing and only two sentences per page provide a format that is easy to read. The text provides a description of the variety of ways that animals use their bottoms, and photographs show examples of nine of these ways. Animals sit on their bottoms and use them to communicate to other animals. Skunks have a unique way of communicating with their bottoms that is unforgettable. Koala bears have soft bottoms, but bees have sharp stingers on their bottoms. Eggs come out of a chicken's bottoms, and starfish eat with their bottoms. A glossary, suggested reading and Internet sites are supplemental materials that boost the appeal of this well-designed and entertaining book.
