I like this listing of ice breakers. Many would work in a language classroom with some tweaking, depending on the level. I like 2, 7, and 9 for novice low-mid students.
I really like the list in the article, but I realized how many possibilities there are for this tool after looking at the Disco Library tab on the top of the page (if you are looking in a PC). There are so many pre-made activities, and you can add them to your grids. Easy peasy, and you don't have to reinvent the wheel!
Although this article is not specifically about teaching a world language class AND it is written by someone who is promoting a product (2 strkes against the article!), it does succinctly share 4 tools to improve the synchronous aspects of a course.
The activity we did with FlipGrid at the beginning of the course was similar in purpose to doing an icebreaker activity in Zoom. Even though our small group interactions were asynchronous, having those visual interactions with FlipGrid and other tools helped make me feel more connected with my coursemates.
