        MATH TOOLS NEWSLETTER - FEBRUARY 8, 2008 - No. 60

  ***FREE ONLINE OPPORTUNITY FOR TEACHERS OF GRADES 5-9
  Using Technology and Problem Solving to Build
    Algebraic Reasoning
  http://mathforum.org/nsdl_mathtech/online/
  The Math Forum has been hosting a series of online workshops
  for teachers who work with students in 5th through 9th grade.
  Teachers are exploring how technology can help students build
  algebraic reasoning as they model and solve contextualized
  problems using a variety of representations, including graphs,
  tables, equations, and words.

  Each participant's $100 workshop fee is being covered by a
  National Science Foundation (NSF) grant, affording participants
  the convenience of anytime, anywhere online learning.

  The next workshop will be offered March 3 - April 12.
  Certificates of completion will be available for participants
  finishing the six weeks of interaction. For an overview with
  additional detalis, visit:

  Deadline for applications is Monday, February 25, 2008.

  ***FEATURED TOOL
  Tool: The Futures Channel
  Jenna Bowles, Editor
  http://mathforum.org/mathtools/tool/36244/
  The Futures Channel produces educational micro-documentary
  videos that show students how professionals are using math,
  science, technology and engineering in the real world.
  Teachers often describe the movies as an answer to that
  famous question, "Why do I need to learn this?"

  ***FEATURED TOOL
  Tool: LSRL, Residual Plots, Data Transformation in Sketchpad
  Nate Burchell
  http://mathforum.org/mathtools/tool/36550/
  Drag seven independent points on a scatterplot, or send
  them to predetermined arrangements, to enhance understanding
  of correlation and the implication of changes.

  ***FEATURED TOOL
  Tool: Taylor and Maclaurin Polynomials on Sketchpad
  Nate Burchell
  http://mathforum.org/mathtools/tool/36557/
  This Sketch allows the user to see the first ten Taylor
  (or Maclaurin) polynomials for a function.

  ***FEATURED DISCUSSION
  Physical models of surfaces
  http://mathforum.org/mathtools/discuss.html?&do=m&thread=g_____g-24
  Peter Ash explains, "I would like to obtain an actual physical
  model of a surface exhibiting negative curvature."

  ***FEATURED DISCUSSION
  Use of Video
  http://mathforum.org/mathtools/discuss.html?&do=r&msg=36106
  MrT68 writes, "Here is a website I created using some of mine.
  I have also loaded them at teachertube and put together a
  website for our school's benchmark exams."

  ***FEATURED DISCUSSION
  Curve of Best Fit for Car's Skidding Distance
  http://mathforum.org/mathtools/discuss.html?&do=m&thread=a2_____g-4
  Jesdisciple asks, "Chapter 8 in the Texas Drivers Handbook
  lists the distance a car will skid after the breaks are
  applied as (MPH, feet). Does anyone have an idea how to
  solve this?"
