As soon as I ended listening to "Song for Someone" by U2, I was immediately flooded with a great tenderness and I thought of all those sensitive students, our society often labels wrongly as weak or unable, and I picked it up to create a worksheet that could be used in our classroom, especially with those that may sometimes be quite troublesome. The lyrics are fairly accessible to students at a lower level and you can use them, in revising not only modals, but also simple present or would/should.
Level: starter/ pre-intermediate
Grammar focus on: can, could, should
Activity: fill in the song with the missing modal verb
Lyrics taken from: http://www.azlyrics.com/lyrics/u2/songforsomeone.html
Tip: if you wish to sing along with your class, why don't you give a look at this version with subtitles?
