This lesson plan discusses a student's school. It begins with warmup questions about students' schools. Then there is a listening exercise about a girl named Carol describing her school, which has three floors, classrooms on each floor, a library, computer room, gym, and bookshop. Students must come to school on time, learn lessons, and do homework. They also have fun time. New vocabulary is introduced about obligations using "must" and prohibitions using "mustn't". Students are assigned to write about their own school and make a poster with school rules using must/mustn't. A rubric is provided to evaluate the posters. The lesson contains material from the textbook "Blue skies for Bulgaria".
