Prepare and deliver an expressive read-aloud of the published narrative, and practice audience etiquette as a listener.
Reading your own work aloud well is a skill separate from writing it. Expression -- changing pace, volume, and tone to match the story's mood -- helps listeners feel the same tension and emotion you built on the page. Practicing aloud beforehand, more than once, makes a real difference.
Reading night is also about being a good audience member: listening actively, staying quiet during others' readings, and offering genuine, specific praise afterward, the same kind of specific feedback practiced in the revision workshop.
Mastery looks like: They deliver an expressive read-aloud with varied pace and volume, and give specific, genuine praise as an audience member.
Common stumbles: Reading in a flat, unvaried voice throughout; giving only generic praise ("that was good") instead of naming a specific moment.
