Recently I've been seeing lots of questions from teachers looking for ways to incorporate some classic collaborations like exquisite corpse. It is, after all that weird time of year where many of us have a short week ahead, maybe some half days or conferences and you're trying to even things out. Grades are probably due and you need a fun break.
While I do have an answer for your exquisite corpse quandary (hint, templates and contact points) why not use this time to expand our art teacher resource bank of collaborative art activities. I recall a fun idea from Ian Sands including post it note mosaics/murals many years ago. Assign each student a color, let them add to a giant wall sized mural. Use the smaller 1" size and break it into 3-4 smaller murals. Great article on murals here. Ian's lesson is available for free here.

Some clever teachers are reinventing this lesson by having students work in shared documents like google sheets to take turns filling in blocks of color to create their images. Some are assigning students into breakout rooms and giving timed contests.
What about a collaborative collage? In this lesson, students are reinforcing their working definitions of juxtaposition, positive and negative space, as well as texture and pattern. Students can share an original drawing or photo of their choice to a folder or space in your virtual classroom. Other students choose a picture that inspires them and they cut out a piece. It is their job to fill the void with a new pattern on texture by holding the photo in front of a variety of objects.
It is great fun for students to see their reimagined photo. Like a Flat Stanley for the art room! For this lesson have students look at the work of Shamekh Bluwi, the inspiration for this lesson.
