This was such a fun activity when I did it with my 9th graders! You'll find a graphic organizer for students, a list of thematically-charged quotations from The Old Man and the Sea, and a Teacher's Guide with two options on how to pull this off with your class.
The main idea is getting students really diving into the rich quotations from this novel and using the process of categorization to come to universal theme conclusions. They will work in groups and share their findings with the class.
Everything you need is here- just print and go! This strategy will work for other novels, as well.
