Program Leader Opening at the Math Forum

http://mathforum.org/announce/programleader_06.html

Looking for a new way to express your interests in math, education, and technology? The Math Forum is hiring to fill the position of Program Leader. The Program Leader is responsible for developing and managing online mathematics education services and research projects of the Math Forum @ Drexel.


Math Forum Discussions Back Online

http://mathforum.org/kb/

We've revived our discussion software -- and in the process caught up our web archives on messages posted during the outage.

E-mail notifications associated with the "watch" function do not yet work. We look forward to resolving this remaining problem, and upgrading our discussion software, early in the new year.


NSDL Online Teacher Workshops

http://mathforum.org/nsdl_mathtech/

Starting in January, the Math Forum will host the first in a series of online workshops for teachers who work with students in 5th through 9th grade.

Teachers will explore 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.

The workshop fees will be covered by a National Science Foundation (NSF) grant, and afford participants the convenience of anytime, anywhere online learning. There are a limited number of openings for our first six-week workshop.

Workshop 1: Using Technology and Problem Solving to Build Algebraic Reasoning

Week 1: January 7 - 13
Week 2: January 14 - 20
Week 3: January 21 - 27
Week 4: January 28 - February 3
Week 5: February 4 - 10
Week 6: February 11 - 17

If you are interested in participating in the first workshop or future workshops, please register:

Giant Fractal Pecan Pie

http://www.instructables.com/id/E5JZ3ILC4AEP2877E4/

The creators of this tutorial explain that they wanted to figure out how to design a large pie that still strikes a balance between the filling (area) and the crust (perimeter).

View the steps they took to construct an enormous pecan pie in the shape of a Koch snowflake fractal, including:

  • intro
  • layout design
  • cut sheet metal to shape
  • attach rim
  • build oven
  • make crust
  • mix filling
  • cook
  • enjoy

Instructables is a website where people share what they do and how they do it, and learn from and collaborate with others. All of the website's illustrated tutorials, called Instructables, are free.


Fractals

Learn about fractals such as the Sierpinski triangle, the Koch edge, the Peano curve, the Lorenz attractor, and the Dragon curve.
