```      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
person.

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

***FEATURED TOOL
Factor Tree
National Library of Virtual Manipulatives
http://mathforum.org/mathtools/tool.html?id=415
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
numbers.
RELATED DISCUSSION:
http://mathforum.org/mathtools/discuss.html?id=415&context=tool
Pre-service teachers discuss uses of the tool. Do you
have ideas to add to the discussion based on your
classroom experience?

***FEATURED TOOL
Coin Toss - Heads in a Row
National Library of Virtual Manipulatives
http://mathforum.org/mathtools/tool.html?id=3060
Explore probability concepts by simulating repeated
coin tosses.
RELATED DISCUSSION:
http://mathforum.org/mathtools/discuss.html?id=3060&context=tool
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.

***FEATURED DISCUSSION
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?
