I recently worked with a high school teacher who was looking for a way to migrate her Google Slide decks to Jamboard to allow her to annotate them with her iPad. This will give her "Zoomies" and her "Roomies" a better visual experience during synchronous teaching. Take a peek and let me know what you think!
I had a teacher ask me if there was a way to hide or remove students who are no longer in your class. The answer is maybe. It depends on if they are officially dropped from your class and appearing as red in your roster and gradebook. If not, then no, you cannot remove them until they have been unenrolled from the class. If the student is showing up as red in your gradebook though, you can hide them so you don't have to worry about them. Here is a screenshot to help you do it:
