In short: Five minute videos that are funny and fun to watch. They make learning English enjoyable.
Each video contains a single grammar point and a theme (Cooking, Interviews, etc.). A narrator reviews the grammar and theme, and then introduces a short video where two people talk about the theme and use the grammar. Then, the narrator reviews the video and some practice exercises.
For students: If you enjoy these videos, you might want to use EF for online lessons. You can learn more here.
For teachers: If you look through the videos, you’ll probably be able to find the grammar point or theme you’re doing in class. You could assign it as homework or use it as part of your lesson.
