Gr 3-6--This series does an excellent job of using past and present sports figures to show how statistics can prove a player's worth. Each book begins with a chapter on "The Basics," covering the area, perimeter, or length of the court, rink, track, or playing field and other calculations (scoring angles, etc.) that apply to the sport. Chapters that focus on statistics, athletes, and famous competitions follow. Most spreads consist of a few computation questions with explanations of the answers and a large, engaging photo with an informative caption. The problem-solving requires some advanced thinking. Most of the exercises use basic math operations along with calculating percentages (although two errors were found). Numerous charts and graphs compare top players and teams. Students who want to know why their favorite players are the best will love these books.[Page 106]. (c) Copyright 2013. Library Journals LLC, a wholly owned subsidiary of Media Source, Inc.
