Happy by Pharrell Williams is such a cool song. It's had over 170,000,000 views on youtube as well so your students will obviously love it. If you haven't taught your students phonetics yet, then have a look at ways to teach phonetics.
There are a couple ways you can do this lesson.
1- Students listen to the song first and try to fill the gaps. Then put the words in the correct columns and listen again.
2- Students look at the missing words first and put them in the correct columns. Then listen to the song and complete the gaps.
3- This song has something extra with connected speech where the students have to find examples of words joining together.
I've prepared the song with numbered gaps, an activity to put the words in the correct column, plus the full lyrics and answers. I plan to get my students to learn the chorus and sing it a few times. Everything is on this word document: Happy - Pharrell Williams
Have fun and be happy!
