MATH AROUND US - FROM KIDPROJ AT KIDLINK
Project Moderators: Laurie Williams and Dennis Buccola
http://www.kidlink.org/KIDPROJ/Math97
MATH AROUND US offers a new activity each month designed
to help show how math is a part of our everyday lives.
Activities planned for October-May 1998 include:
OCT MATH CURSE REVISITED
In Jon Scieszka's book _Math Curse_, a little girl
wakes up feeling she's been cursed, a "math curse"
because she sees everything that happens to her
as some sort of math problem. Students think of
their lives 'mathematically', seeing how many ways
they can find math problems throughout the day.
On the list, they share *their* 'math curse' days.
NOV Math in Careers
DEC Personal Measurement
JAN Mapping It Out
FEB Math in the News
MAR Make Math Fit
APR Wait a Minute!
MAY We're Coming for a Visit
Visit the project's Web page to find out more and register
to join. Registration is open all year long, so you can
join one or all of the featured activities.

CONTINUED FRACTIONS
Selected Web sites that offer varied perspectives on these
interesting fractions:
- CONTINUED FRACTIONS - CALVIN COLLEGE
http://www.calvin.edu/academic/math/confrac/index.html
A site designed for college undergraduates and offering
an explanation, some history, theory, applications, and
a bibliography.
- AN INTRODUCTION TO CONTINUED FRACTIONS - RON KNOTT
http://www.mcs.surrey.ac.uk/Personal/R.Knott/Fibonacci/cfINTRO.html
"Continued fractions are just another way of writing
fractions. They have some interesting links with a jigsaw-
puzzle problem of splitting a rectangle up into squares
and also with one of the oldest algorithms known to
mathematicians - Euclid's Algorithm for computing greatest
common divisors (gcd)..."
- CONTINUED FRACTIONS, INFINITE CONTINUED FRACTIONS, AND
ITERATION - THE MATHMAN
http://www.shout.net/~mathman/html/prob8a.html
An area of mathematics with applications to population
increase, finding square roots, chaos theory, and fractals.
Sample problems from Chapter 8 of Don Cohen's "Iteration
to Infinite Sequences with 6 to 11 year-olds."

- PIANOS AND CONTINUED FRACTIONS - EDWARD DUNNE & MARK MCCONNELL
http://www.math.okstate.edu/~dunne/students/Temperament.html
It is an old (and well-understood) problem in music that
you can't tune a piano perfectly. This paper provides an
interesting discussion of the physics (acoustics),
mathematics, and temperament of pianos, with references
and definitions.
