1- Hang-outs
2- Circles
This is another great feature that teachers should capitalize on . You can for instance create a circle for your classroom and start sharing on it things related to that class. Additionally, you can create circles based on different categories and subject matters, like a circle for social studies class, or a circle for class announcements …etc.
3- Google Plus for group work
You can guide your students on how to create their own circles and add members to it.They can then use these circles to work collaboratively with each group being able to see the live stream of the other. They can also chat and comment on their learning as they work in groups.
