Used originally as a "time filler" for that last 5 minutes of class, my students started to LOVE doing these exercises and even requesting them. I pick which verb tense I want them to focus on and they give a short story or review statement of the video.
This Power Point contains short video clips with audio (all G-rated) on each slide. There is also "helper vocabulary" associated with each video to help students integrate new words and feel like they can express their ideas completely.
This can be utilized in many formats: individual warm-up to class, group vs. group, cool-downs, assessments.... You can chose to give points for communicating meaning, correct verb usage, and/or creativity. (We do a lot of high-5's in class)
