My thanks to those of you who came to my talk and played along with these activities. The links below will get you a copy of the handout and send you directly to the applets themselves.

I would love to get some comments from any of the attendees. Can you name one thing that you took away from the talk that you’re eager to try out or work on?


Exploring (vicariously) interactive applets that let students “notice and wonder”, talk about mathematical situations, and develop conceptual understandings of triangle properties, linear equations, systems of equations, and factoring trinomials.
