The most obvious challenge with this tool is access to a computer lab....but
once there, I can see so many ways to use this.  The lessons described on the
page are excellent.  You could add several more practice problems, but I just
found myself 'playing' with this applet for about 10 minutes...and it was fun!
Wouldn't it be great if your students did that?

There was some talk about how much needed to be 'taught' BEFORE using this
applet.  That depends whether you were investigating graph relationships, or
actually calculating the functions for lines etc.  I think the relationships
need to be understood prior to coming up with functions and actual numbers.  I
think there is real value in 'playing' with the graphs.  The students that I
have taught adapt to this environment very readily.  I find myself having to
'practice' before hand just to keep up with them.  Once they have a good idea
what the graph will look like given certain parameters, THEN I would start the
discussion on what a function would 'look' like.

Thanks...this was fun.
