MATH FORUM INTERNET NEWS
NEW ON OUR SITE =======
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 realworld examples that will be interesting to their students. Stories by topic (Archeology through Zoology) and by method (ANCOVA through Two sample ttest); 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 K12 math question via the Web or send email to dr.math@forum.swarthmore.edu. A member of our 'Swat Team' of math doctors will reply via email, so be sure to send us the right email address. K12 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? http://forum.swarthmore.edu/dr.math/problems/schulz11.20.html

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 geometryprecollege where we post the Geometry Problem of the Week and Project of the Month, both targeted at high school students. The other, geometrypuzzles, attracts less regular postings of higherlevel 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/InterLinks/puzzles.html http://www.mathpro.com/math/mathCenter.html.
I hope that helps. Thanks for writing in!
