I like the song "Let's Go Fly a Kite" for a number of lessons. There's a film clip from Mary Poppins on Youtube that you can show which has subtitles. However, for learning the song, I thought more was needed that simply Karaoke-type subtitles. Although I am working on a PPT song with lyrics for "Let's Go Fly a Kite", it's not quite done yet. In the meantime, please enjoy part one of the "Let's Go Fly a Kite" Q and A.
Please view this slowly with F5 first to get an idea of how it's supposed to proceed. You can go down the rows and ask the students questions based on the slides (some questions are presented for you). To the consternation of my co-teacher, I encourage my students to respond by saying "I don't know" when faced with a question they don't know the answer to, or simply don't understand. (My co-teacher wishes to only ask questions that ALL students can answer every time.) I try to pitch the questions so that some can and some can't answer, and work off the creative tension. If the students are lively, I might call for volunteers instead of marching down the aisles one after another.
In any event, the goal is to get the students singing the song, understanding the lyrics, and picturing the meanings in their head (with absolutely no code-switching confusions over Hangul). Whether it is better to do this by presenting the whole song at once, or in pieces as I have started here, I have no idea. Please let us know how this works for you; emendations are welcome.
It may be worthwhile, somewhere down the road on this lesson plan, to bring a kite into the classroom, perch it up in the corner, and have one of the students hold on to the string while they sing.
