Begin to explore the Geometer's Sketchpad the easy way - two
entertaining labs from Mike Reidy, for individuals or to use
in the classroom (middle school and beyond):
Introductory Sketchpad Lab
http://forum.swarthmore.edu/sketchpad/intro/gsp.introlab.html
Intermediate GSP Lab: Spirograph Machine/"Tea Cusps and Saucers"
http://forum.swarthmore.edu/sketchpad/intro/cusplab.toc.html
This lab studies the effects (both mathematical and artistic)
of circular motion as points rotate around circles. Interesting
things occur when a point moves around a circle as the circle
rotates around another circle.

FEATURED INTERNET RESOURCE

The Data and Story Library (DASL)
http://lib.stat.cmu.edu/DASL/
Teachers often ask for - but frequently have to create for
themselves - good data collections for students to analyze.
DASL is an online searchable library of datafiles and stories that
illustrate the use of basic statistics methods, providing data
from a wide variety of topics so that statistics teachers can find
real-world examples that will be interesting to their students.
Stories by topic (Archeology through Zoology) and by method
(ANCOVA through Two sample t-test); datafiles by subject
(Agriculture through Weather). A form is available for submitting
your story.
Pat Daley, one of our advanced institute participants, is working on a
set of related web pages known as the Data Library:

ASK DR. MATH - AN INTERACTIVE INTERNET PROJECT
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Is your math assignment driving you crazy?
Submit your K-12 math question via the Web or send e-mail to
dr.math@forum.swarthmore.edu. A member of our 'Swat Team'
of math doctors will reply via e-mail, so be sure to send us
the right e-mail address. K-12 questions usually include what
people learn in the U.S. from the time they're 5 years old
through when they're about 18.
A SEARCHABLE ARCHIVE of questions and answers is available. You
may find that your problem has already been answered - some of
the same questions arrive regularly. Here are a few examples:
Why is a negative times a negative a positive?
http://forum.swarthmore.edu/dr.math/problems/neg.times.neg.html
Why was the letter m selected to represent slope?
http://forum.swarthmore.edu/dr.math/problems/m.for.slope.html
Where did the missing dollar go?

FROM THE EMAILBAG... (letters, we get letters...)
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
The Suggestion Box at the bottom of our home page is a regular
source of good questions like this one:
Could you please send me some information on mailing lists that
have math problems? - TheOlusola@aol.com
:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:.:
Sure thing.
The Forum administers two mailing lists that regularly feature
math problems. The first is geometry-pre-college where we post
the Geometry Problem of the Week and Project of the Month, both
targeted at high school students. The other, geometry-puzzles,
attracts less regular postings of higher-level geometry problems.
Instructions for subscribing to these lists and reading the
archives: http://forum.swarthmore.edu/access.html
The "Talking Math" section of the Teachers' Place is a good place
on our site for general information about math mailing lists:
http://forum.swarthmore.edu/teachers/k12.discussions.html
and there are problem and puzzle pages in our Student Center:
http://forum.swarthmore.edu/students/students.high.probs.html
The "Classroom Materials" section of our Teachers' Place also
highlights some puzzle and problem pages, including the rec.puzzles
archives and the Internet Center for Math Problems:
http://forum.swarthmore.edu/teachers/k12.classroom.html
http://www.nova.edu/Inter-Links/puzzles.html
http://www.mathpro.com/math/mathCenter.html.
I hope that helps. Thanks for writing in!
