The first strategy I would highly recommend for this assignment is making index cards. As you read through the story, each time you encounter a specific locale, make up an index card containing:
- A short name or description for the locale
- The page number where it first occurs
- A two- or three-sentence description of what happens in the place.
As you encounter places additional times, just add the additional page numbers and descriptions onto the index cards. By the time you have reached the end of the story, you will have completed the assignment. The key is having a very organized process rather than just trying to skim over the story and remember all the places that are mentioned.
The starting place for the story is Sanger Rainsford's yacht. Next, we have the ocean through which he swims. Then we encounter the exterior of the house. When we see the inside of the house, every room can count as a distinct place. During the hunt itself, we see several different parts of the island. The story concludes in Zaroff's bedroom.
