Presenter: Patrick Callahan

Summary:

The above item from the 2007 NAEP was one of the most difficult. Why was it so difficult? What are some of the challenges students have connecting geometry and algebra? We will explore geometric transformations in school mathematics and analyze how student thinking can evolve from informal experiential definitions and strategies into more robust formal approaches. We will investigate how students can apply geometric transformations to be more successful in solving geometric problems.

Registration Open: Closes April 24th

Duration: 60 minutes

Format: Online seminar via Zoom web meeting software with questions and discussion. Detailed instructions for joining the seminar will be emailed to registered participants.
