# Math in Spring and Summer Sports

In the springtime, some middle school students enjoy outdoor sports much more than they enjoy their math classes. Why not use two of these popular sports to our advantage in the classroom? The following problems with baseball and track themes challenge students to exercise some of the skills they learn in the middle school curriculum.

What Is Round, Hard and Sold for \$3 Million?
This activity challenges students to determine which is worth more today: Babe Ruth’s 1927 home-run record-breaking ball or Mark McGwire’s 70th home-run ball that sold in 1999 for \$3 million. Compound interest is the main topic.

Who’s On First Today?
In this activity, students use hits and at-bat statistics to determine which of two baseball players has a better batting average.

Fun with Baseball Stats
In this lesson plan, students use baseball cards to convert statistics to decimals, fractions and percentages. Then, they use their statistics in playing a game. Activity sheets can be downloaded.

Can You Run As Fast As a Car?
This activity asks the student to determine if Florence Griffith-Joyner moved faster than a car traveling 15 miles per hour when she ran 10 meters at a record-breaking 0.91 seconds during the Seoul Olympics. Along with the answer, students will find a description of how to make unit conversions and other problems related to conversions of units of measure for volume, distance, currency, and temperature.

We want and need your ideas, suggestions, and observations. What
would you like to know more about? What questions have your
students asked? We invite you to share with us and other readers
you think and tell us how we can serve you better. We appreciate
your feedback on all of our Middle School Portal 2

# Distance-Rate-Time

Measurement is one of the core NCTM Principals and Standards for School Mathematics content standards, and rate is central to its practical application. While most middle school students know the distance-rate-time formula, they may still benefit from a closer study of the relationship.

Understanding Distance, Speed, and Time Relationships
Students see two runners move along a track. As they change the speeds and starting points of the runners, they watch the race but also examine a graph of the time-versus-distance relationship. Excellent questions guide the class as they investigate the scenario from several angles.
