EdPuzzle
Edpuzzle is an online tool you can use to create interactive videos. After logging into Edpuzzle, you can copy a link to a video on YouTube and trim it to focus on just the section you want. Then, at certain points in the video, you can add questions that students have to answer before being able to continue watching the video. The free version allows you to create 5 video "Edpuzzles" which you can share with your students.
