Students study the format of a business letter. To make it "real" for students, they have an opportunity to choose someone famous person (a band, singer, writer, movie star, etc) to write to.
Students draft their letter, peer edit, and then type their letter and fill out their envelopes then I mail them out.
Students who receive letters back (they are sent to the school) they open them and share with the rest of the class. It is wonderful and the kids LOVE it.
Here is a picture of what Emma received back!
