This lesson plan is for a 25-minute listening and speaking lesson at CLB level 4 about saying goodbye. The lesson uses a song from The Sound of Music called "So Long, Farewell" to teach vocabulary for saying goodbye in English. Learners will do warmup activities, pre-listening tasks to predict the story and learn vocabulary, during-listening tasks to understand the gist and details of the song, and a post-listening speaking activity where learners individually say how they would say goodbye and what they would miss most about the class.
