[Free Registration/Login Required] A three-lesson unit on author's purpose. In the first lesson, students practice identifying the author's purpose as to entertain, to persuade, or to inform. In the second lesson, students use graphic organizers to identify the author's purpose as well as evidence from the text. The third lesson teaches students to distinguish the purpose of texts on the same topic that have written by different authors. All texts and student handouts for this lesson are available with free login.
