```         MATH TOOLS NEWSLETTER - MARCH 5, 2005 - No. 24

We have added a new Technology problem (tPoW) to Math Tools.
Feel free to have students submit their solutions to us

***FEATURED TPOW
Technology PoW: Runners
http://mathforum.org/mathtools/tpow/17540/
Tell how a runner's step size predicts the time it takes
to run from the building to the tree. A link to a Java
applet from NCTM's "Electronic Examples, Principles and
Standards for School Mathematics" is provided to help students

***FEATURED DISCUSSION
Tool Usage Sites
Tackweed asks, "Would those of you who have current web pages
where various math tools are used by classes/students please
provide the url? I am looking for specific tool use in context
as opposed to listings of tools."

***FEATURED DISCUSSION
Formulas
Mrs. J comments, "I have noticed over the last few years that
students are having more difficulty with the concept of formulas.
Am I alone or have others seen this problem?"

***FEATURED DISCUSSION
The NEW Classroom
Susan asks, "I have a friend who has the opportunity to give input
on purchases for all the new mathematics classroom.  What should
she buy in the way of technology? Think ten years out because
the funds may disappear!"

***FEATURED ACTIVITY
Activity: A Lulu of a Function
Craig Russell
http://mathforum.org/mathtools/activity/17629/
This activity guides exploration of functional aspects of the
Lulu microworld. Functions called for are not y = f(x) functions;
domains/ranges are either directions or coordinates of points.

***FEATURED ACTIVITY
Activity: Analysis of Bivariate Data Using Fathom
Freudenthal Institute
http://mathforum.org/mathtools/activity/17471/
The resource consists of a series of linked concept maps
that lead students through steps of importing and analyzing
two-variable data using Fathom. Students follow illustrated
steps to import data from Internet sites, create graphs,
calculate statistical measures, and create a report. A further
data set is assigned for a project to be handed in using the
same steps. Designed for Ontario Curriculum Grade 12 Data
Management (MDM 4U0).
