Flipgrid is a platform that allows teachers to post questions or topics or start a conversation and then students can contribute their thoughts through posting a video response. The tool allows students to customize their response and use face-blocking tools, if they wish. The video is taken and stored in the Flipgrid cloud software so need to worry about large files that will not load into Google Classroom or email. Flipgrid creates a sense of a shared community.
Teachers can create accounts to set up class pages. Students do not need an account; students simply enter the code provided by the teacher.
