It is a really interesting way to study and practise simple past tense with your students. Divide class into 3 groups. Each group picks a number in turn. They see a picture of a famous singer when she/he was a child including Selena Gomez,Lady Gaga,Brithney Spears,Ellie Goulding,Christina Aguilera,Michael Jackson,Madonna,Ricky Martin,Eminem,Beyonce,Demi Lovato,Pink. They read what they did in the past (wikipedia facts). They listen to sample songs and the teacher talks about them using simple past tense. Students try to guess the singer. The group that guesses more is the winner.
