Here you have got the corresponding sound file to help you work with the song.
Part 2: Score with silent bars
1- Now you have got the score with some silent bars. Start singing the notes and remain silent when the bars with no notes appear. Try to start in time to follow the melody.
2- Half the class uses glockenspiels to play the melody while the other half sings the lyrics. Be careful with silent bars as you have to keep on singing even if there is no music! When you finish, change turns.
Here you have the sound file to help you.
