I used this worksheet when my class learnt about superheroes. I printed the picture in A3 format and covered it with small cards (with the help of some blue tac). I numbered the cards and told my students that every number belongs to a task. (They had to say a word or expression in English or they had to translate a sentence.) When they managed the task properly I took off one card. They had to guess what was under the cards. After that students listened to the song and filled the gaps.
