In my junior one (7th graders) advance class, I taught them an English song, titled "Tomorrow" by Amy Diamond. Students have to change the original song into their own words. After they changed it, they have to sing the song aloud. Personally, I am not a music teacher, so I do not expect them to sing perfectly.
All of them are so creative, I am really enjoying their singing performances.
