I was able to find all sort of information about the Polls App for mobile phones. That sounds like a great tool, but it's not what I'm looking for. I'm not looking to get a real-time answer to a question from students using their phones during class. I just want to put up a poll on the Canvas page for the course so that I can get some feedback from the students on their own time. Is there a way to do this through Canvas, or am I stuck using an outside tool?
