Geogebra introduction

Hello from Audrey! Thanks for trying out the flipped class, or in this case the flipped webinar. On April 20th, I'll be talking about how I flip my high school classes. One of the tools I use is geogebra. If you are reading this before the webinar, you will not only learn a bit about geogebra, but you will also get an idea of what it's like to be a student in a flipped class, where you can arrive already knowing something. I hope you enjoy both aspects of that!
