This series explores the lives and careers of some of the greatest athletes alive. The books use short paragraphs of easy-to-read text and colorful photos to showcase these exciting athletes. Each book also includes a table of contents, fun facts, sidebars, comprehension questions, a glossary, an index, and a list of resources for further reading. Apex books have low reading levels (grades 2-3) but are designed for older students, with interest levels of grades 3-7.
