July 10 Cross Country Collaboration - Tina Cardone

Summary:
Shireen Dadmehr (PCMI alum and math blogger at http://mathteachermambo.blogspot.com/) and Tina Cardone (PCMI participant and math blogger at http://DrawingOnMath.blogspot.com) worked together on a Cross Country Collaboration. We paired up our students, one from Texas and one from Massachusetts and assigned them the task of creating a teaching/assessing tool for their peers. The projects they created are visible at: http://cardonemath.com/CCC.html. The biggest impact of this project is invisible though, it is the understanding students gained on remote communication and working together.

July 11 www.deltamath.com - Sara Rezvi

Summary:
This 5 minute short will show a web 2.0 tool developed by a fellow Math for America colleague, Zach Korzyk, called www.deltamath.com. The website uses learning targets to hone in on skill sets that students oftentimes have trouble with. The purpose of my short is to show how to use the site, and the various intricacies that the website holds.

July 12 Teacher2Teacher (T2T®) - Gail Englert

Summary:
As a Teacher2Teacher Associate, I've volunteered my time since May 11, 1998 to respond to questions submitted to this free service offered by the Math Forum. We're looking for folks who might be interested in joining me as Suzanne and I think about how this service could be used to help teachers with questions they have about the CCSSM.

July 13 Math Mistakes - Gabriel Rosenberg

Summary:
One of Ashli's tweeps, Michael Pershan, just started a new project called Math Mistakes. His own description of the project sums it up well: Teachers need to be able to quickly look at mathematical work and identify the assumptions behind the work, and what actions to take in response to the work. That's hard. But practice can help us get better at this. The idea is that on this site each post will be a selection of student work. That student work will be posted by me, but sent in by you. And then in the comments we'll discuss: what are the assumptions behind this work, and what could the next steps be.

July 19 IberoCabrí 2012 - Troy Jones

Summary:
Troy summarized a presentation that he will give in Spanish at the VI Congreso Iberoamericano de Cabrí (IberoCabrí 2012) in Lima, Perú the second week of August. His presentation will review the points of concurrency in a triangle and extend these to their analogs in a tetrahedron. The Euler Line and 9-point circle relationships will also be extended to their analogous cases in a tetrahedron.
