Elementary schoolers are charged with writing an article for their peers. A class discussion yields topics about which learners consider themselves to be an expert. The teacher models how to construct an article by using facts he or she has written down on index cards about something they are an expert about. The cards are organized in an understandable fashion, and the process of writing the article begins. This kind of expository writing is very important to include in your teaching year, and the instructional activity outlined here will provide your pupils with a good opportunity for writing.
