AMTNYS in Rochester

I will be giving a short presentation on "The Power of GeoGebra" at the AMTNYS conference in Rochester next month. I am gathering a selection of my creations to use as examples. You can see the collection as it grows by clicking here.

Pentagoning the Square???

This was created to help show that GeoGebra can be used to create presentations for the classroom. I certainly wish I had this when I was a classroom teacher!!

This particular one shows how a regular pentagon (equal sides, equal angles!) can be created from a square.
Have fun!!

I will be talking about this and a lot about GeoGebra in general at my presentation at AMTNYS in Rochester (currently I am scheduled at 3:45 on Sept. 12. See you there!!
