This lesson plan focuses on teaching British and American slang terms through various activities. Students will learn new slang words, practice them in sample dialogues, read a text about how young Brits speak slang, and listen to a song by Lil Dicky to identify slang terms. They will also have the opportunity to compose their own dialogues using slang words and discuss agreeing or disagreeing in speech if time allows. The 50-minute lesson involves warm-up discussion, presentations, readings, exercises and a listening activity to engage students in actively learning and using slang terminology.
