How skilled are you at observing, listening, and then responding? Check out these flipgrids from a teacher in Australia, Joyce Brownwyn. She and her students would love it if you added to their conversation.
Consider adding your voice - feel free to write your small script (these can only be up to 30 seconds or up to 3 minutes) and record it in class at our recording station located under the clock.
Use what you've observed, use responses from other participants as your guide, and be respectful and responsible. You are representing our class, and we want to be able to have this privilege in the future.
