Flipgrid is a video-based discussion platform you can use to engage your students in a wide variety of learning experiences. The way it works is very simple: as a teacher you create a grid for your class, then you add a topic for discussion and students share their responses in short recorded videos. Students can also view and reply to each others video feedback and build a dynamic interactive learning community.
