ASU Software Downloads - The university makes some mathematics software available for students, faculty and staff. Note especially Maple, Mathematica, and MATLAB for mathematics. Also, you might check out the Anti Virus Software, SSH for secure file transfer and remote login, and SAS, SPSS, or R (online only) for statistical analysis.

GeoGebra - This is a free open-source dynamic algebra and geometry package. It will do most of the things that Sketchpad will.

VPython - Is a 3D module built on top of the object-oriented programming language Python. It is a simple language that allows for rapid development of visual models of dynamic events using fundamental physical and mathematical principles.

NCTM - The National Council of Teachers of Mathematics.  The Principles & Standards are available online as well as their "Illuminations," resources to aid in teaching standards-based lessons.

Arizona Standards - The state sets its own standards which are directly linked to the AIMS test. The Arizona Standards are important for you to understand so you can ensure that all of the necessary content is covered.

U.S. Department of Education - The DOE site contains useful information regarding education standards in general and what types of things teachers can do in their classrooms regarding, for example, technology and assessment.

The Geometry Center - Has several interesting animations and interactive geometry visualizations.

Rice University - Has lesson plans that can be used at a variety of different levels of mathematics and that utilize a variety of different approaches.

The Math Forum - A host of great resources, from lesson plans and teacher bulleting boards to collections of articles on various issues in education policy.  A particularly popular spot is their Ask Dr. Math page.  You should spend some time here poking around to familiarize yourself with what is available.

Algebra I Assessments - Provides teachers with assessment tasks, including connections to Texas and national standards; guiding questions; model solutions; and sample student work to help teachers understand what their students know about Algebra I content. Includes 25 core problems and 50 supplementary tasks.

Mathematical Models - A resource from The University of Texas with eight units covering modeling of various real-world phenomena.

MegaMath - A Los Alamos Labs project that introduces unusual and cool math concepts.

MathWorld - A great site to look up various mathematical terms and concepts in an encyclopedia-style format.
