Imagery is one of the most prominent literary features in Maya Angelou's memoir, I Know Why the Caged Bird Sings.
This carefully-crafted handout introduces (or reintroduces!) students to the concept of imagery, provides examples of imagery both in Angelou's text and in famous poems, and then challenges students to explore imagery in an assigned section of the memoir and look for imagery patterns (in a graphic organizer provided on the handout).
I use this activity after reading chapters 17-19, because those are imagery-laden chapters, but with a few clicks it could be adapted for other chapters or for the book as a whole. I put students in small groups and ask each group to work through a particular section of the book and then report back to the class on what they find.
