New Problems of the Week Site and Software
The Math Forum @ Drexel is looking forward to the launch of new Problems of the Week software that will be faster, more reliable, and easier to use.
NOTE: In order to complete the transition and testing of the
new system, our Problems of the Week services will not be
available from Friday, July 31 through Tuesday, August 4. There
will be no access to any part of any of the PoW services during
that period: current problems, Library, Write Math, student
registration, teacher offices, etc. will all be closed. We
apologize for any inconvenience this disruption might cause.

PCMI Statistics Activities
These statistics activities involving Fathom software were
developed as part of the Park City Mathematics Institute, or
PCMI. This year's institute is currently under way.
Our Backpack Data: Making Conclusions from Graphs
This small-group activity with whole-class discussion and
optional use of Fathom software involves graphing data from
a survey of guessed vs. actual weight of backpacks.
Let 'Em Roll™ Simulation
In this activity, students calculate experimental and
theoretical probabilities in a dice game in which both
mutually exclusive and dependent events occur.
Parabolic Path to a Best Best-Fit Line
Students experiment with the underlying quadratic relationship
between slope and residuals to find the least squares
regression line in this activity.

We host a public discussion group on Fathom and Tinkerplots
software, available online (or by RSS) here:
The Math Dude
As the Math Dude, Mike DeGraba engages students with his video
explanations of Algebra I concepts. The 5- to 7-minute episodes
are available via Flash on the web, podcast, RSS feed, and—if
you live in Montgomery County, MD—cable TV. Episodes are
produced to coordinate with Montgomery County's curriculum
timetable, but are available on demand from the site.
