T³ International Conference
Seattle, Washington
February 27 - March 1, 2009

Thanks to everyone who stopped by our exhibit in Seattle, and to everyone who's stopping by virtually now! We had a great time problem solving with you!

Below are blank versions of the activities we featured. We've also posted the noticings and wonderings you generated: ferris_wheel_t3.tns.zip. Enjoy!

If you're interested in learning more about doing "noticing and wondering" and other problem-solving activities with your students, consider a membership in our Problems of the Week that includes access to our new Problem Solving and Communication Activity Series. "Noticing and wondering" is one of the Understanding the Problem activities.

ferris_wheel.tns.zip Notice and wonder about quantities and relationships as a cab moves around a ferris wheel, then develop a mathematical model based on what the noticing and wondering.   gear_ratio.tns.zip Notice and wonder as you observe a unicycle with a changeable gear ratio. Note: this activity is still in development! What might we ask students to do next? How could the construction be improved?   midpoint_quad.tns.zip Notice and wonder about a changeable midpoint quadrilateral, then add "auxiliary lines" and notice and wonder again.
