The program I like to use to communicate and collaborate with my students is bitpaper.io. This application allows my students and I to both work on the same whiteboard in real time and communicate through video, audio, and/or chatting. It also allows you to input documents that can be annotated right on your device (i.e. homework, worksheets, etc.)! When finished, BitPaper makes it easy for you to print and/or save for easy studying! Visit https://bitpaper.io/features to learn more! All instructions on how to use this application (It is actually really easy to use!) will be sent to your email immediately after booking. Of course if you don't feel comfortable using this application, we can always communicate another way, but it wont be as effective as using BitPaper (I promise it is easy to use!).
