       MATH TOOLS NEWSLETTER - SEPTEMBER 3, 2005 - No. 31

  Thank you to everyone who participated in our Special Events
  held each week in August. We hope everyone joins in the
  continuing discussions!

  ***FEATURED TPOW
  Technology PoW: A Million Penny Project
  Cynthia Lanius
  http://mathforum.org/mathtools/tpow/18198/
  Students use a spreadsheet to show when they will have
  collected their million pennies.

  ***FEATURED DISCUSSION
  ICMI Study 17 on "Technology Revisited"
  http://mathforum.org/mathtools/discuss.html?&do=m&thread=_____g-84
  John Olive encourages "those of you who work within the
  mathematics education community to consider contributing
  to this ICMI study on technology." In his post he provides
  a link to a document to download more information.

  ***FEATURED DISCUSSION
  TI83 Graphing Calculator Online
  http://mathforum.org/mathtools/discuss.html?&do=m&thread=_____g-82
  Mary asks, "I would like my students to access through the
  Internet or as a software package that can be installed on
  a computer a program that acts like a TI83 or TI84 graphing
  calculator. Does anyone know of such a program?"

  ***FEATURED DISCUSSION
  Analyzing how Tools are used: Stories and Reviews from the Field
  http://mathforum.org/mathtools/discuss.html?&do=m&thread=_____g-79
  Gene writes, "Some folks think that writing stories is really
  a bit daunting and it's harder to see how it directly relates
  to your teaching."

  ***FEATURED TOOL
  Tool: eNLVM - Interactive Online Math Lessons
  Utah State University
  http://mathforum.org/mathtools/tool/20291/
  The eNLVM enhances the applets available through the
  National Library of Virtual Manipulatives (NLVM). It allows
  teachers to embed applets in lessons, make up questions to
  which students can submit answers online, and compare the
  answers thus submitted. Teachers may also choose to use or
  adapt existing lesson plans.

  ***FEATURED TOOL
  Tool: Linear Lasers
  Ankur Dalal and Eric Meyers
  http://mathforum.org/mathtools/tool/20367/
  This project uses Java and Flash technologies to graphically
  represent the concept of linear functions (of the form
  y = mx + b). The project has four sections, including a
  demonstration, pre-think, Java-based game and a wrap-up
  section.

  ***FEATURED TOOL
  Tool: ODE Toolkit
  Harvey Mudd College
  http://mathforum.org/mathtools/tool/20344/
  ODE Toolkit can numerically find and display the solutions
  to differential equations. It is useful when you want to
  visualize the solutions to differential equations, or when
  analytic solutions are not available. ODE Toolkit is a
  Java-based program available on the web that runs on
  Linux, Mac OS X and most Windows platforms.

  ***FEATURED STORY
  Story: Side Length and Area of Similar Figures
  Jeff LeMieux
  http://mathforum.org/mathtools/lesson/20245/
  The subjects of this story are the two applets 'Side Length
  and Area of Similar Figures' and 'Side Length, Volume, and
  Surface Area of Similar Solids.' These two applets help
  demonstrate the relationships listed in the titles, also
  known as scale factor and similarity.

  ***FEATURED SUPPORT MATERIAL
  Support Material: Probability
  Kirsten Anderson, Learningwave
  http://mathforum.org/mathtools/support/20226/
  Collection of illustrated descriptions, with problems for
  students to work out, for automated feedback.
