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 site for updates: http://mathforum.org/mathtools/ Last summer's first Tool Fest took place in Philadelphia, August 2-6.

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.
