Put the class in 4 groups (or 8 if it is more appropriate) and ask them to prepare to retell the stories of Pocahontas, The Little Mermaid, Aladdin and Beauty and the Beast.
You can set this as homework, so students can use the Internet to find any missing facts.
Regroup students so that in each group there is at least one person with each story so they can remind their classmates of the plots. These are well known stories, so they can support each other in retelling them.
Ask students how all all the stories and when they see that the endings are similar, ask them to come up with a group short story of their life after the ending. Regroup them again so that they can share their new endings.
show them the video of the song and have them compare their endings. In groups, they help each other with the difficult vocabulary. Have dictionaries ready for this part.
Discuss what the author wanted to express with his video. You can have them do this in groups and present orally or respond in writing, depending on your needs.
