Sports is perfect for making lists. Who's the fastest? Who has the most wins? Who's the best? In this high-interest series, readers will learn about heroes from a wide variety of sports. They'll read facts, stats, and true stories, and then form their own opinions as to who's Number 1--learning the difference between facts and opinions along the way. A great series for reluctant readers! Outstanding photography, fact-packed sidebars and captions, a table of contents, a phonetic glossary, sources for further research, an index, and an introduction to the author all aid readers' comprehension.
