This packet breaks the novel into three parts with a sheet of questions for each segment. The questions with the first segment (up to page 25) aim to help students to grasp necessary points of the exposition; later questions try to push students toward a deeper analysis.
Additional note: I include the question about how Santiago can tell the fish is male because it is actually impossible to tell without dissection, and Hemingway knew it. If you can find a copy of Robert Weeks' essay "A Lack of Realism Mars Hemingway's Old Man and the Sea," he discusses this point at length. It leads to interesting class discussions.
