GAFE is a service that was created by google specifically for use by educators and students. These apps include include Gmail, Hangouts, Google Calendar, Drive, Docs, Sheets, Slides, Groups, News, Play, and Sites.
This is a tool that was created by google in collaboration with educators to manage and distribute course work, assignments, grades, and feedback to students. The process of making and being the administrator of a google classroom is streamlined. It is a free easy to use tool that allows teachers to use their time in more constructive ways.
Is a way for students to collaboratively work on an assignment simultaneously from different locations. I personally use google docs for everything I do in school and personally think it is one of the most important applications while doing collaborative group work. It allows us to utilize our time more efficiently and gives us the ability to fit group work into our busy schedules easier.
