You can use this activity as a warmer after having taught Future verb tenses.

– Watch the video beforehand in order to select the best moments to pause it.
– Then, in class, whenever you pause the video, ask sts “What´s HE going to do next?” to elicit sentences with GOING TO.
– Show the part and see who guessed the right action.
– Do the same thing, at various moments of the video.

The video-activity is short, fun and interesting.
