Flipgrid is one of my favorite tools to recommend to other teachers. It is an all-around great tool, providing for differentiation, student voice, engagement, peer feedback, and saving time. It is made for students to quickly and easily join and record their videos. This is a game changer in the classroom, especially for those students who hate to write. They can discuss, share ideas, provide proofs, and explain. Then, they have fun ways to dress up their videos with stickers and filters. For those students that are even more self-conscious, they can use the white board instead of recording their own face. It is easy for teachers to use, too. They have their own login to manage their grids that make it easy to respond to the students. If you have a problem, the people supporting FlipMakesLearningEngaging are so helpful. They really do want it to work well for you. Just look at all the great reviews they have gotten.
