This assignment was created to be used along with a story/article called "Kilimanjaro!" that was in a book of non-fiction. However, I can't seem to find the story (from 1957) or the anthology. Good news is that it doesn't really matter, since the main point was to take a story told from the European/American perspective and change it to that of the African porters.
While I have not read Hemingway's "Snows of Kilimanjaro," if that story is told from a white male point of view, the assignment will work fine. And you don't have to worry, it's not really about race or racism; it's just about people being different and caring about different things.
Students enjoyed this assignment, and that's not always the case with assignments designed force students to think about others. It could be made into a group work assignment with small adjustments.
Two options, both with photos to help drive creative thinking. No rubric but a list of required elements.
