***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?"
