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?




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: 

Our Teachers' Place also highlights some puzzle and problem pages, 
including the rec.puzzles archives and the Internet Center for Math 

I hope that helps.  Thanks for writing in!
