Rehearse this line with the students: There are still _bottles of pop on the wall.Divide the class into nine groups. Assign a number to each group, from one to eight, with the ninth group assigned the words “no more” (the equivalent of zero, per the last verse).

The whole class sings the first three lines of each verse together, and then each group speaks its assigned line at the appropriate point.The class will listen to the audiotape to learn the song. First, the students should just listen to the audiotape. The second time the Song plays, they should sing along.
