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.
