Here are my answers to #1 on the Web part of the homework.
I've included three math sites plus one non-math site that I found interesting.
(I did not include any of the many cool things you can find on The Geometry
Center's web site.)

1.  Torus and Klein Bottle Games

    http://www.northnet.org/weeks/TorusGames/TorusGames.html

These are cool interactive Java games.  You can play traditional board games
like Tic-Tac-Toe or Chess on the the surface of a torus or a Klein bottle.
(If you like challenging jigsaw puzzles, you'll love the Klein bottle jigsaw
puzzle.)

Hypertext allows you to pick topics in the order you choose, instead of going
through them in sequential order.  Java allows interaction with these web pages,
which is the key to the success of the activities.


2.  Mathmania

    http://csr.uvic.ca/~mmania/ 

This is a nicely organized site with activities for Knots, Graphs,
Sorting Networks and Finite State Machines.  They even list real-world
applications for each of the topics.

As in the Torus activities, hypertext allows you to go through the activities
in any order.  There are lots of animations (e.g. untying a knot) that show
concepts that would be impossible to show with still images. 


3.  The Uselessness of Pi Page

    http://www.go2net.com/internet/useless/useless/pi.html 

What's useless to some is useful to others.  This page is a collection of
information about Pi and memorizing the digits of Pi.  Did you know that
there's a club for people who have memorized at least 1000 digits of Pi?
Do you know what the world's record for most digits of Pi memorized is?
I actually found this site useful last Pi Day (3/14).  In my math class we
had a contest to see who could memorize the most digits of Pi.  This site
gave several techniques that different people have used to do it.  

It makes use of hypertext (albeit a rather weak use) by being a collection of
links to many different Web sites.  


Just for fun:  The WebCrawler SearchTicker

    http://webcrawler.com/WebCrawler/SearchTicker.html 

This addictive web page has nothing to do with Math.  Using Java it displays
ticker tape of the real things that people are searching for on the
WebCrawler search engine.  Supposedly this is live, but I did my own search
and never saw it show up.
