There are two nonfiction writing styles—narrative or expository. Here are some examples:
Life stories generally have a narrative writing style. These books tell a true story or convey an experience. They feature characters, settings, and scenes. Ideally, they have rising tension, a climax, and denouement.
Concept books generally have an expository writing style. These books describe, explain, or inform in a clear, accessible fashion. They include data, facts, ideas, and patterns that allow students to learn about the world and how it works.
Once you select a writing style, you can think about text structure. That’s what I’ll focus on next week.
