I don't use slideshows to share content with students, but I have found one really excellent use of Google Slides for my purposes: I create a slideshow each semester of the student projects in each of my classes, and then I combine the slides in both shows for a presentation of all the projects across both classes.
I also got a randomizer add-on so that I can randomize the order of the slides (I try to do that daily if I remember) so that they're in a different order, with everybody having an equally random chance of coming early in the show.
I then embed this slideshow in various places: it's part of our class projects pages, for example, and I embed the shows in Canvas, and it's also in the sidebar of the Daily Announcements blog! Here you can see how it looks in Canvas:
This type of slideshow is also a great example of distributed content: when I update the order of the slideshow, the latest version is what will load and appear here, along with everywhere else I have embedded the slideshow.
