```          MATH TOOLS NEWSLETTER - June 4, 2005 - No. 27

Math Tools will hold a Remote Math and Technology Tool Fest
June 13 - 17 with the purpose of virtually getting together
a group of folks to:

- rate resources
- submit resources
- write reviews
- write stories
- seed and participate in discussions
- have virtual presentations of favorite tools and
interesting math

http://mathforum.org/workshops/toolfest05/introfest.html

We have gathered a group of stakeholders in mathematics,
education, and technology who enjoy collaborating across
different school levels and technology interests. As the
Tool Fest activities begin on Monday, June 13, we hope
that you will join in the discussions! Watch the Math Tools

Last summer's first Tool Fest took place in Philadelphia,
August 2-6. View the site:

***FEATURED TPOW
Technology PoW: Mauna Loa
http://mathforum.org/mathtools/tpow/18177/
Using the monthly measurement data for 1975 through 1988 from
Mauna Loa, predict the CO2 level for your birthday in the current
year. Data can be downloaded in a Fathom file or the data can be
accessed from a web site.

***FEATURED TPOW
Technology PoW: Types of Triangles
http://mathforum.org/mathtools/tpow/18196/
Students use a GSP sketch or an interactive web page to drag and
manipulate four triangles. They identify one of each type: scalene,
isosceles, equilateral, and right.

***FEATURED ACTIVITY
Activity: Instant Solution of a Maze
David Chandler
http://mathforum.org/mathtools/tool/19021/
A quick way to find solutions to complicated mazes. The author
writes: "While doing a maze activity with a group of elementary
school homeschoolers, I started exploring mazes as systems of
walls rather than as systems of paths. Each maze is at least two
separate wall systems. By pulling an image of a maze into a paint
program or photo editing program (I use LView), each wall system
can be colored by the flood-fill option. Islands of walls not
attached to either side thus become obvious and all possible
paths can be traced by walking only along paths that border two
colors. I have an illustration of the result at the URL listed
here."

***FEATURED TOOL
Tool: Experiment with the Ferris Wheel
Leslie Nielsen
http://mathforum.org/mathtools/tool/18732/
These sketches created with Geometer's Sketchpad were originally
written to go with problem CF 21 in the CPM Algebra 2 book.

***FEATURED TOOL
Tool: Origami Construction
David Chandler
http://mathforum.org/mathtools/tool/18749/
By following step-by-step instructions to fold a sheet of paper,
construct a mathematically correct regular pentagon.
