Start by looking at the front cover. Look at what you can see. Discuss the who the author and illustrator are. Now ask some of these questions to your child:
What do you think the book might be about?
What do you think might happen?
Can you describe the characters you can see?
Where do you think the story takes place?
How do you think the characters feel? Why might they feel this way?
Can you point to the title?
