Sometimes you miss class, or you need a reminder on last week's lesson. For the most part, you should be able to watch recordings of your past classes. This article describes where you can find them.
Log into Canvas and click into the course in question.
Go to the Zoom section in your course. You can do this by either clicking Zoom in the left-hand menu, or clicking the Zoom icon in the homepage.
This is the section where you normally join your Zoom class. But if you click the Cloud Recordings tab, you'll see the recordings of all your past classes. Find the day you want to watch, and click the blue topic next to it.
Click the gray recording icon. It will open a new tab with the video of your class from that day.
