Freestyle question: ~
Have you tried Story Chains from Grandomastery with your students? We've been organizing zoom contests based on https://www.grandomastery.com/story and it has been such fun so far. Later on I will upload the videos of the stories they make, upon my students' permission of course. Grandomastery seems to be a great tool for Advanced learners in particular. They have other types of activities, for example, Random Advertisement and Random Magnets, but Random Story is still our favourite.
