The Old Man and the Sea...please help

Hello,

I need to teach a class tonight based on this book. However, I have no idea how to teach a class based on ANY book.

Does anybody have recommendations as to what I can do with two students for one hour? They were supposed to already read the book and then write an essay.

Honestly, I'm horrible with grappling with the idea of symbolism and that stuff. PLEASE HELP!!!
