 ``` 2 October 2000 Vol. 5, No. 40 THE MATH FORUM INTERNET NEWS Mathematical Tale Winds | Parrondo's Games Math Solutions Online Newsletters MATHEMATICAL TALE WINDS - Jerry Ameis http://www.uwinnipeg.ca/~jameis/ Ameis embeds routine and non-routine mathematical problems in short and long stories to show how elementary school children can be encouraged to solve them. Contents include: - Concept stories for grades 2-3, designed to help develop concepts such as area - Land of Pome story problems for grades 2-4, situated in the fantasy land of Pome - Journey to the island of Dread, a fantasy adventure story for grades 3-4, with 80 math problems - Circle of Flame, a growing fantasy adventure story that has math problems for grades 3-4 and perhaps 5. A chapter is added every couple of months. Notes for teachers and parents are provided. Dr. Ameis is a member of the Faculty of Education at the University of Winnipeg, Manitoba, Canada. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- PARRONDO'S GAMES - Greg Harmer http://www.eleceng.adelaide.edu.au/Personal/gpharmer/games/ The paradox of Parrondo: to lose + to lose = to win. Juan Manuel Rodriguez Parrondo devised two simple mathematical games of chance that are of interest to experts in diverse areas of science. Their results are surprising in statistical terms: to play any one of the two separately supposes losing; however, if a player alternates games in certain or random combinations, he or she wins - an effect known as "Parrondo's Paradox." The site includes pages on Brownian Ratchets, Parrondo's Games, and more, including Feynman's ratchet and pawl device, a mathematical analysis of the games using discrete-time Markov chains, a note on the entropies of Parrondo's games, and a list of papers. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- MATH SOLUTIONS ONLINE NEWSLETTERS Marilyn Burns Education Associates http://www.mathsolutions.com/frames/n_newsletter_frame.html A newsletter designed to provide up-to-date classroom activities and Math Solutions programs and materials for elementary and middle-school students. Articles by Marilyn Burns and others offer ideas ranging from how to help children make sense of money and dates, to ways of using writing to help students learn. Suggestions for parent conferences and a brief history of trends in mathematics education ("Math for the 21st Century - Back to Basics?") are also provided. The newsletter is published twice a year by Marilyn Burns, and you are invited to add yourself to the Math Solutions mailing list. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- 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/ Mathematics Library http://mathforum.org/library/ 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\ / \ / \ / | / \ / \ ```
