MATH, BASEBALL, AND THE SAN FRANCISCO GIANTS
Linda Uhrenholt, Pacific Bell Education First
http://www.kn.pacbell.com/wired/baseball/
An interdisciplinary unit for elementary and middle school
students by a fan who was first taken to a game by her aunt.
Students answer questions and follow links to Internet sites
to research the cost of travel expenses, food, and tickets,
determining the cost of attending a Giants game, the time
it takes to get to the park, and more.
Guided questions and useful links are provided for a variety
of problems, including:
 sabermetrics (the mathematics of the game of baseball)
 ticket pricing
 peanuts and french fries
 attendance and food
 salaries and statistics
 buying Giants magazines
 payrolls and salaries
 individual batting averages
 team batting averages
 bats and balls
 earned run averages
 Hall of Fame tshirts
 cleaning up the trash
 Pacific Bell Park construction
In conclusion, students write reports itemizing their total
expenses at the game, find examples of math used in baseball
not touched on in the activities, and construct their own
definitions of baseball.

WORMS is a grassroots, userdriven WWW site established by
the Operations Research Group (ORG) of the Department of
Mathematics, University of Melbourne, Australia. WORMS' main
objective is to complement the formal online activities of
OR/MS societies worldwide. Features include JavaORjavA (see
what JavaScript and OR can do together); jokes and anecdotes,
FAQs, a mathematical programming glossary, and more.
