One way to get students thinking about point of view is to make them realize that any story is different if told from a different perspective. Have students rewrite a story you have studied from the perspective of a character. For younger students, use a fairy tale such as "The Three Little Pigs" and have students write from the perspective of the wolf. For older students, allow them to choose a minor character from a novel you have studied. Tell students that the trick is to make an unsympathetic character seem sympathetic.
You should constantly remind your students that all literary texts are told from a specific perspective, even if the author is unaware of it. Break your class into small groups. Read the first paragraph or page of a story out loud. Have the groups discuss the narrator's perspective. They should think about elements such as gender, age, nationality or anything else. For "objective" narrators, students should consider biases that the narrator has, who he decides to focus on and anything else that indicates a subjective point of view.
You can teach point of view by having students share their own subjective experiences of a common event. Wait until your class goes on a fun field trip or attends a stimulating assembly. Have each student write a journal entry narrating the day's events. When they are done, go around the room and have each student read his journal entry out loud. Discuss the variety of perspectives on the same event, including how and why different people can feel vastly different things about a common experience.
Dramatic exercises can be a fun way to teach students about point of view in literature. After you have read a novel or story together, ask for a student volunteer to play one of the characters from the text. Have another student interview her by asking questions about her experiences in the story. Have the first student improvise responses. After the interviewer is out of questions, allow the rest of the class to ask questions. Repeat the exercise with another student playing a different character.
