Google In Classroom

I am a physical education teacher so the thought of google in the classroom hadn't really crossed my mind until watching this training. I think it would be an excellent way to keep in touch with parents and also a great way to keep in contact with students if they were absent that day from class. The students could get the lesson of that day from me and they could in turn send me their "proof" of completing the workout. I also feel that this would be a great way to email athletes and parents all at the same time.
