I used this song with students of the 1st ESO (to teach) and 2nd ESO (to revise) the difference between the present simple and the past simple.
Worksheet 1: We talk about Kelly Clarkson to introduce the song.
Worksheet 2: Cut the song into pieces. They have to order the song while listening. They can work in pairs.
Worksheet 3: It is a fill in the gap activity. Students can work in pairs and use a dictionary if necessary.
Worksheet 4: We watch the video with lyrics so they can check their answers.
Worksheet 5: I ask them questions about the song.
