This Italian lesson for ninth graders focuses on the use of the imperfect tense, known as “imperfetto,” in sentences to describe actions that occurred repeatedly in the past. The instructor explains the importance of the conjunction “mentre,” meaning “while,” as a signal for using the imperfect tense, and provides examples to illustrate its application. Students will engage with a text about music and learn how to formulate questions based on it by the end of the lesson.
