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 Shakira,Katy Perry,Amy Winehouse,Paris Hilton,Avril Lavigne,Jennifer Lopez,50 cent,Pharrel Williams,Taylor Swift,Justin Bieber,Enrique İglesias,Miley Cyrus. 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.
