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 t-shirts - 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. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- ONLINE MATH APPLICATIONS Leung, Jiang, Jiang, Chiu, Klopfer, Chiu ThinkQuest Junior 1998 http://tqjunior.advanced.org/4116/ Activities, examples, problems, and online quizzes about math applied to real world situations, created by a team of 5th and 6th graders with their teacher-coaches: - Investing http://tqjunior.advanced.org/4116/Investing/investin.htm Learn real-life math using a variety of investment vehicles: compound interest, bank deposits, CDs, stocks, bonds, and mutual funds. - Music http://tqjunior.advanced.org/4116/Music/music.htm What does math have to do with music?

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. http://www.maths.mu.oz.au/~worms/ -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CHECK OUT OUR WEB SITE: The Math Forum http://mathforum.org/ Ask Dr. Math http://mathforum.org/dr.math/ Problems of the Week http://mathforum.org/pow/ Internet Resources http://mathforum.org/~steve/ Teacher2Teacher http://mathforum.org/t2t/ Discussion Groups http://mathforum.org/discussions/ Join the Math Forum http://mathforum.org/join.forum.html Send comments to the Math Forum Internet Newsletter editors _o \o_ __| \ / |__ o _ o/ \o/ __|- __/ \__/o \o | o/ o/__/ /\ /| | \ \ / \ / \ /o\ / \ / \ / | / \ / \ ```
