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.

Seafloor Spreading

Seafloor spreading can be a difficult concept for middle school students to grasp. These resources should help make the concept comprehensible through the use of images and animations and by acknowledging the concept’s larger context of plate tectonics.

Harry Hess: One of the Discoverers of Seafloor Spreading
This detailed biography shows how Hess’s skills enabled him to contribute to the scientific knowledge base of seafloor spreading and how his observations, models and predictions support the theory of plate tectonics.

The Distance Between Us and Them: Seafloor Spreading in the Atlantic Ocean
In this activity, students gain an understanding of how geologists determine rates of seafloor spreading. Using a strip map of the North Atlantic seafloor, students measure distances and note the ages of the strips of basalt. They also gain experience in applying mathematical concepts such as calculation and use of velocities and conversion from one set of units to another.

Seafloor Spreading
This page, part of the NeMO project, provides a concise explanation and a graphic representation of seafloor spreading and its relationship to divergent tectonic plates. Related links at the bottom of page include a link to mid-ocean trenches.

This Dynamic Earth: The Story of Plate Tectonics
This free, online booklet, containing photos and graphic illustrations, puts the idea of seafloor spreading in the larger context of plate tectonics.

Interactive Animation of Seafloor Spreading and Magnetic Field Reversals
Earth’s magnetic field reverses itself from time to time; North becomes South and South becomes North. Rocks on the seafloor on either side of a mid-ocean spreading ridge preserve a record of the Earth’s magnetic field over time. This page also shows how distance from the ridge is related to age or time.
