Follow-up stage. The follow-up stage should attempt to build on the successful completion of the core stage. In other words, the students have sung the song and now should be encouraged to use the vocabulary or sentence structures from the song. Again, this depends on the circumstances of the teacher. The follow-up stage could be used to develop written production, either through writing sentences or gap-fill activities, or oral production where the vocabulary learned is used in a situational role-play.
