      MATH TOOLS NEWSLETTER - MAY 1, 2004 - No. 14

  We enjoyed meeting and talking with many of you who
  attended our presentations and visited our exhibit
  booth during the annual meeting of the National Council
  of Teachers of Mathematics. It was great to be able to
  receive user feedback about the Math Tools site in

  We are excited to unveil a new feature: Technology PoW,
  affectionately known as the tPoW. Link to the tPoW by
  looking at the right sidebar, under RESOURCES, and
  clicking "Problems."

  Technology problems (tPows) are modeled on the Math
  Forum's Problems of the Week, with the additional
  feature that the problems take advantage of an
  interactive mathematics tool. We are planning to add
  more tPoWs soon. Feel free to have students submit
  solutions to us following the "Submit your answer" link.

  Factor Tree
  National Library of Virtual Manipulatives
  This manipulative allows you to construct factor trees
  for two numbers, and then from that prime factorization,
  asks you to identify the Least Common Multiple (LCM)
  and the Greatest Common Factor (GCF) of the two given
  Pre-service teachers discuss uses of the tool. Do you
  have ideas to add to the discussion based on your
  classroom experience?

  Coin Toss - Heads in a Row
  National Library of Virtual Manipulatives
  Explore probability concepts by simulating repeated
  coin tosses.
  In discussing this cataloged resource, an inservice
  teacher recommends some as-yet uncataloged tools that
  allow for custom-tailored instructions, lessons, or
  activities. He also cautions that some sites might
  contain too much or too little information, depending
  on the level of the student.

  General Discussion: Frustrations
  Math Tools users reflect on differences between tools
  used in Japan vs the United States.
  How do you use technology in your classroom? Do students
  work independently using technology? Do you use
  technology as part of your explanation of material?
