This PowerPoint is an overview of the 3 types of writing within common core: narrative, argumentative, and informative. There is an informational slide for each type of writing which includes the definition, characteristics and format. There is also a visual graphic organizer to represent each of the three types of writing. The end of the lesson is designed for students to compare and contrast the the three areas, noting their similarities and differences. I'm using this as a wrap-up of for writing and as a review before testing, but could also be used to preview writing.
This is geared toward 8th grade Common Core standards, but could easily be adapted.
