MATH TOOLS NEWSLETTER - JANUARY 4, 2008 - No. 59
***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 January 14 - February 23.
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, January 7, 2008.

***FEATURED TPOW
TI-PoW: Chirp! Chirp!
Annie Fetter, Heidi Rudolph
http://mathforum.org/mathtools/tpow/35755/
Use your TI-Nspire to find the temperature when a cricket
chirps a certain number of times a minute.
***FEATURED TPOW
TI-PoW: Sam and Teri's Bank Accounts
Terry Trotter, Steve Weimar, and Heidi Rudolph
http://mathforum.org/mathtools/tpow/35757/
Use your TI-Nspire to consider this scenario and question:
Sam and Teri have bank accounts. Sam always withdraws money;
Teri always saves it. When will they have equal balances --
or will they ever?
***FEATURED TOOL
Tool: Volume Inside a Cube - Math Open Reference
John Page
http://mathforum.org/mathtools/tool/35664/
An interactive applet and associated web page that demonstrate
the volume of a cube. A cube is shown where the edge length can
be changed by dragging. The volume is continuously recalculated
as you drag, and a unit cube grid is superimposed on the cube
to illustrate the volume graphically. The calculations can be
turned off for class discussion.
***FEATURED TOOL
Tool: Rational Equations Visualizer
Dennis Sullivan
http://mathforum.org/mathtools/tool/35277/
Explore how the parameters in a rational equation affect the
graph of the equation. Dynamically change the parameters and
immediately see how the graph changes. Undefined points are
clearly visible. Try to change the parameters so the graph of
the equation matches a given graph.
***FEATURED TOOL
Tool: Archimy.com - 3D Graphs Online
Denis Kozyr
http://mathforum.org/mathtools/tool/35533/
Archimy.com is a service for drawing the graphs of all kinds
of functions.
***FEATURED DISCUSSION
Resource Suggestions for Sketchpad

JimS writes, "I would appreciate any suggestions of sources
for Sketchpad lessons that incorporate a Smartboard."
***FEATURED DISCUSSION
technology
http://mathforum.org/mathtools/discuss.html?&do=m&thread=___tool__g-13
kristinams explains, "I am trying to integrate some new technology
into my classroom, I teach HS Algebra. I would like to start a
blog or have students create math videos that I could post on a
webpage. Has anyone done a project like this?"
