```        MATH TOOLS NEWSLETTER - AUGUST 7, 2004 - No. 17

Twenty-one participants who traveled to Philadelphia and
twenty-four online members of the Math Tools community spent
last week getting familiar with the recently implemented
features of the Math Tools site. They have collaborated to
create classroom activities, software-related resources, and
services for themselves and others.

***FEATURED DISCUSSION
Teaching Mathematics as a Science
Bethany writes, "It seems that the pervading philosophy of
teaching and learning mathematics is pushing us as educators [...]
to make math more of a discovery process than just giving students
the concepts and trying to process them.... What do you think?

***FEATURED DISCUSSION
few other people have chimed in so far. He writes, "I'm fairly
new to the Math Tools community, and I thought it would be useful
if some of you 'longer-timers' would share your N favorite tools
cataloged on the site (I'm thinking like your top 10, but any value
of N would be fine)."

***FEATURED DISCUSSION
Traffic Jam Activity
The Traffic Jam Activity was our first Tool Fest activity. Read
comments noted during our face-to-face discussion and also
thoughts posted by the community as they tried the activity.

***FEATURED TOOL
Tool: Parabola in Standard Form (Java Sketchpad version)
Annie Fetter
http://mathforum.org/mathtools/tool.html?id=12142
This applet, created with Java Sketchpad, allows the exploration
of a parabola in standard form, where the coefficients a, b, and c
are restricted to multiples of 1/2. A sister sketch allows
unrestricted coefficients.

***FEATURED TOOL
Tool: Parabola in Standard Form (Sketch)
Annie Fetter
http://mathforum.org/mathtools/tool.html?id=12146
This sketch allows the manipulation of a parabola in standard form.
On the first page, the coefficients a, b, and c are restricted to
multiples of 0.5. On the second page, they are unrestricted and
can be set to exact numbers using the "fine controls."

***FEATURED TOOL
Tool: Centers of Triangles
Wing Kuen Cheng
http://mathforum.org/mathtools/tool.html?id=12260
See the different centers of a triangle and how they relate
to the medians, perpendicular bisectors, and altitudes of the
triangle. Students can manipulate the triangle and try to answer
the follow-up questions at the bottom.
