Are you looking for a way to poll your class? Have you checked out Dotstorming? Dotstorming was built for people to share ideas in the form of digital sticky notes and then vote for their favorite ideas. It works well for that purpose. Students do not need to have email addresses in order to vote on notes posted on Dotstorming. A free account allows you to have three topic boards at a time. The paid account ($5/month) gives you unlimited access. There is also a school-wide pricing plan. Watch Richard Byrne’s video to learn how to use Dotstorming.
