added a new option to Google+ in the form of polls. Google+ polls allow you to create a poll to share with the whole world, one of your circles, or members of one of your Google+ communities. You can add multiple pictures to your poll to add a visual component to your questions and answer choices. Your poll respondents can add comments to the poll just as they can with any other Google+ discussion. That option allows people to explain their votes on the poll.

Applications for Education
If you're using Google+ Communities to communicate with students, Google+ polls could be a good way to quickly gather feedback about a question that you pose to them. Encourage your students to use the comments to explain their votes and the poll could serve as a great discussion starter.
