With edpuzzle, teachers can use videos (from YouTube or self-created) and add questions and notes throughout to check for understanding. It integrates with Google Classroom and has tons of teacher-created Edpuzzles ready to be assigned.
Live mode can also be used. For live mode, teachers can go through the video with everyone in a class at once and Edpuzzle will track responses.
