Dr. Mark Daniels talked about iterative processes applied to geometric figures. Participants then created 3-D objects by using an iterative process implemented with paper cutting and folding.
The handout from the session, as well as the flyer for the UTeach Teacher Preparation Academy are posted below.

The 15-puzzle is the
perennial puzzle consisting of 15 numbered tiles on a 4 by 4 square that need
to be restored to the standard ordering by sliding the tiles around. It is what
is called a permutation puzzle, just like its more famous cousin: the Rubik's
cube. We will consider the general form of the 15-puzzle and the crucial role
played by the parity of permutations, something that Sam Loyd, "America's
greatest puzzler" in the words of Martin Gardner, knew how to exploit to
great effect. |

Beyond Odd and Even:
A Creative Way of
Looking at Parity
Presented
by
Jason Ermer
The
University of Texas at Austin October 27, 2011
Mathematics teachers know the
"official" definitions and concepts that comprise school mathematics,
but our students may see things differently. Where might their creative mathematical thinking lead us? See the handouts below for a new
look at some familiar mathematics, and for extensions that will stretch your own
creative mathematical thinking! |

Random Surprises: Expect the Unexpected
September 29, 2011 (NOA 1.102)
Presented by Dr. Michael Starbird
The University of Texas at Austin
What should we expect from random
chance? The answer is full of surprises. Whether we flip a coin, look at data,
or ask for birthdays, we find that our intuition about what to expect is often
far from what actually happens by chance
alone. When dealing with chance, we have to learn to expect the unexpected.

Simple questions about something as routine as carrying
when adding integers can lead to interesting problems and
deep results!

Circle Chords & Cutting Planes
January 27, 2011
NOA 1.102
presented by
Jason Ermer
When we put n points on the boundary of a circle and connect all pairs of points, we divide the circle into regions. If no more than two line segments meet at any one point, how many regions will there be?
Trying this for n = 1, 2, 3, 4, and 5, we see a nice pattern emerging. However there is an unpleasant surprise in store when we test our conjecture for n = 6. This problem is a nice example of why we must be careful when generalizing from special cases to the general case. It is also a challenge to find and justify the real pattern at work here!
