Auto racing is a sport of metal and rubber, but it’s also a game of numbers. From lap times around a track to the speed of each car at qualifying, NASCAR’s unique brand of racing is an easy place to see math in action. Readers learn that different types of tracks are built in different lengths, and how differences in road courses and superspeedways impact speeds. All of these factors are ways to turn those numbers into innovative tools to learn about mathematics in new and exciting ways.
