I begin by letting the students watch the video and ask them to explain how they feel at the end of the video and tell me what the video was about. Students will often say "I feel good" and "it's about being nice".
I then get the students to watch the video again and note down the verbs which could be used to describe the actions seen in the video and compare their list with a partner.
You could then create a list of the phrasal verbs and ask the students to match them with the objects for example:
1) to lose a) a tip
2) to give b) a wallet
3) to fall off c) a skateboard
and so on....
Another task you give the students is a list of nouns, which the students have to look out for in the video e.g:
Students have to look out for these objects, people, places etc in the video and then write a sentence about each one. e.g. A man drops some coins.
Alternatively you can have the words written on cards and students have to sort them to construct the sentence to match the action in the video.
Finally you can round off with students writing a story or discussing what happens in the video.
