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 as-is. 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 10-sided dice to your desktop; then open and play. Visit our plugins page to make sure you've got all the (free) plugins you need.

Overviews, worksheets, slideshows, and tests

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:

More Math PowerPoints
Download and enjoy, snag graphics, even whole slides, or—for the inquisitive—take a look at Custom Animations and see how they were done.

  • Picture this! one-half of six [.ppt]
  • Integers on number lines [.ppt]
  • Perimeter and area [.ppt]
  • Picture this! prisms and cylinders [.ppt]
  • Picture this! reducing fractions with a multiplication table [.ppt]
  • Slope —> 4 ways [.ppt]
  • The Changing Seat Problem—slides and jumps [.ppt]
