Math Resources
Most of these are in three formats—.doc and .docx—so you can edit text and graphics in your own creations and .pdf so you can print things out clearly asis. For tips on creating your own graphics (all these were done in MS Word) see SOESD's computer training pages.
Animations, PowerPoints, and Virtual Manipulatives
Download and save the PowerPoints and virtual 10sided dice to your desktop; then open and play. Visit our plugins page to make sure you've got all the (free) plugins you need.

Race Games and Diffies
Grids, Tables, Dot Paper, Number Lines, Fraction Walls, and Coordinate Axes
In many of these the grid was pasted into the header so it acts like a watermark and lets you draw or type on top without having the graphics squirrel around.

Cutouts: Pattern Blocks, Tangrams, Power Polygons, US Money
The shapes are very good for area—calculating and comparing—and talking about and picturing fractions. And money, naturally, speaks for itself:
