Nice overview of terminology used with quadratic functions and Equations
http://www.edteach.com/algebra/quadratics/quadratic_definitions.htm
Here's
some history on the development of the study
of Quadratic Functions

This
site is about using Algebra Tiles to factor quadratics. There is a link on
this page that tells you how to make your own Algebra Tiles.
And even though she says the "F" word (FOIL) on this page, it is also a nice resource for using Algebra Tiles
Here
is a
leson plan about
factoring and the connection of the factors to the roots of a
quadratic equation. It is similar to what we did in class but
much more detailed. It would be a great tool for you to use in
your classroom and to help you with the final.
Wow! This is a really nice article about the importance of multiple
representations of patterns and functions accross all grade levels.
It is then followed with a set of sample activities to be implemented at various
grade elvels. You can view the website by clicking here.
All the activities can be downloaded as Word files.
Here's a site that has a program to solve quadratics equations...
you just input the coefficients and out come the solutions :)

A
dynamic
applet
that allows you to
change the coeficients and examine the shape of the graph as well
as its roots. When you get to the website go to the Quadratic
Equations 2 Applet

On a slightly different note... here is a great math clip art page (along with lots of great quotes and other stuff)that I found. Thought I would take the chance to share :)
