If you can bring a laptop, please do. If not, let me know in advance, so I can plan accordingly.
I use Macs, so that is the preferred platform for the workshop. However, GeoGebra is available for iOS, Android, and Windows, so you are welcome to bring any device. Just be aware that my ability to help you with non-Mac technicalities will be limited. Moreover, even if you need to use tablets at school, I strongly recommend you bring a laptop, as the software on a computer has more features, is easier to use, and gives you the possibility to easily connect with a projector when you’re back in the classroom.
If you don't have the latest version of GeoGebra, download it here.
Please download GeoGebra before the workshop. And if you can spend some time familiarizing yourself with it, all the better. Remember, this is not an introductory workshop. It is meant to show you features of the software that are especially useful to you as a teacher, and that you may not have come across if you are new to GeoGebra.
If you encounter difficulties, e-mail me and I'll try to help.
