Determining an author's purpose can help readers understand a text more deeply. Using a PIES chart (persuade, inform, entertain, share) and poems from Leaf by Leaf: Autumn Poems by Barbara Rogasky, class members organize lines that show author's purpose. Pupils will have a chance to work as a class and independently. Materials are provided, but require a free membership. The lesson is easily teachable with or without the provided materials.
