Help build Ms. O'Leary's classroom library with the Who Would Win? collection.

This innovative science series introduces young readers to animal species by pitting two creatures against one another and asking kids to predict which one would prevail. Each book is illustrated with vivid, full-color pictures and features two animals that rarely, if ever, meet in the wild. Readers use information about each animal's physical attributes, nearest relatives, diet, survival tactics, and more to determine which creature would win in a fight. With easy-to-navigate layouts and just a few key facts per page, these books encourage kids to draw scientific conclusions by using reasoning skills and creative thinking.
