I found lots of ideas from this page: Narration Starters. I omitted the ones involving writing because we're not there yet (J is in Ambleside Online's Year 2). Here's what I chose:
- Tell me all you remember about the story.
 - What did you like about the story?
 - No narration today!
 - Mummy narrates.
 - Draw a scene or character from the story.
 - Act out a scene from the story.
 - Describe ______. (A character or place from the story.)
 - Ask me a question about the story.
 - Make a model of a scene or character from the story.
 - Tell me something you didn't like about the story.
 - Make a short puppet show of the story.
 - Make a Lego scene from the story.
 - What does the story remind you of?
 - Pick a character: are you the same as or different from them?
 - Find a biblical truth in the story.
 - What do you think will happen next?
 - What would you do if you were in the story?
 - Why did ____________?
 - What do you think about _____________?
 - Do you agree with __________?
