I frequently use videos with Chinese subtitles to supplement textbook content. Using videos requires extensive support in the form of worksheets and online quiz games like Kahoot or Quizlet or Quizizz. Also, I typically reserve these kinds of educational videos for 5th and 6th graders.  If you search through public Quizlet and Kahoot sets for "Professor_Pighead", you might find several games that are designed to exercise listening and vocabulary in these educational videos.

For young kiddos I usually play kids music videos. My favorite Youtube channels are Singing Walrus and Fun Kids English. But sometimes I just browse through Youtube looking for kid friendly MVs like on Sesame Street.

Examples and links to both educational and music videos are below. Play through them in your spare time and think about which ones might fit your students' interests. Make your own playlist that you keep handy and can use anytime you need to warm-up, wind-down, or do an emergency substitute lesson.

P.S. I also download kids MVs on MP3 and play them during cleaning time at school.
