DP Virtual Studio 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 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? How does music affect student performance on tests? What's the Mozart effect? - History http://tqjunior.advanced.org/4116/History/history.htm Math started around 2,000 B.C. - read about such great mathematicians as Euclid, Pascal, Newton, and Gauss, people who developed key concepts in algebra, geometry, trigonometry, and calculus. - Science http://tqjunior.advanced.org/4116/Science/science.htm Study math concepts: the power of doubling, base 2 binary math, unit conversions, and scientific notation. - Trips http://tqjunior.advanced.org/4116/Trip_Planning/trip.htm Carry out a break-even analysis of car rental, explore pattern recognition of routes between cities, calculate the cost tradeoff of driving various sizes of cars, study road safety, and relate braking distance to reaction time. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- DP (DYNAMIC PROGRAMMING) VIRTUAL STUDIO http://www.maths.mu.oz.au/~moshe/dp/DPstudio.html Problems and puzzles from WORMS, the World-Wide-Web for Operations Research and Management Science site directed by "Chief Spider" Moshe Sniedovich: - Knapsack problem - fill a knapsack with available items so as to maximize the total value of the items - Towers of Noah - the Tower of Hanoi, with animals - 8 Easy Pieces - restore the tiles to their original position as quickly as possible - 8 Queens Puzzle - place N queens on an 8x8 chessboard so that they do not attack each other - Travelling Spider Problem - a variation of the travelling salesman problem, in which a spider must visit n Web sites, each only once, commencing and terminating the tour at his/her home site: determine a tour that minimizes the travel time \|/ WORMS is a grassroots, user-driven 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. 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\ / \ / \ / | / \ / \
