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

Intermediate GSP Lab: Spirograph Machine/"Tea Cusps and Saucers"
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.



The Data and Story Library (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:



Is your math assignment driving you crazy?

Submit your K-12 math question via the Web or send e-mail to 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?

Why was the letter m selected to represent slope?

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? -


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

The "Talking Math" section of the Teachers' Place is a good place
on our site for general information about math mailing lists:
and there are problem and puzzle pages in our Student Center:

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:

I hope that helps. Thanks for writing in!
