MATH TOOLS NEWSLETTER - OCTOBER 2, 2004 - No. 19

  At the end of September we added several new features. Each
  individual resource page now identifies the resource's language
  and cost, if any. It will take a little time to edit the resources
  already in Math Tools but we're working on it. In fact, we could
  use your help! If you notice a resource that should be marked as
  a commercial resource, please let us know.

  We've also added a number of new Technology Types, so our full
  list now includes:

    Calculator
      Texas Instruments
    Computer
      Cabri
      Computer Algebra Systems
        Mathematica
      Fathom
      Flash
      Java Applet
      JavaScript
      Presentation software
        PowerPoint
      Shockwave
      Sketchpad
      Spreadsheet
        Excel
    PDA
      Palm OS
      PocketPC

  If you have tools that you can suggest for any of the courses,
  feel free to tell us about them.
