If you are talking about live, real-time, in-class polling, take a look at Canvas Polls Mobile Guides - Polls for Canvas. Otherwise, take a look at the discussions in this feature idea - " modifiedtitle="true" title="Poll option for voting. There is a pretty good example of using some Google services or a service called Wedgies to embed polls on a content page.
Hi @PaulRoselli - Unfortunately, the Polls for Canvas app is no longer available. This was a change that happened in January 2021. Alternatively, you could use sites/tools with HTML embedding options to add polls to any Canvas content. Let us know if you'd like to collaborate or suggest some options.
