This is a massive powerpoint that should last you at least two months. It chronologically teaches American literature from 1400 and ends on Hawthorne (a perfect stopping place if you plan to teach "The Scarlet Letter").
There is a creation story narrative, essay response, editorial (I have the instructions sold in my store), and literary criticism for writing projects in this unit.
Students get background on each author, important terms defined, and questions to each reading. These titles should mostly be in your textbook if you're teaching American lit, and the others are easily found online.
