What Are Picture Walks, You Ask?
Okay, a picture walk is an introduction to a new picture book, using the pictures only. The person leading the walk can ask listeners about what they think is going on in the pictures, who the characters may be, and what they think might happen. Since illustrations are supposed to carry a plot line, this approach should give nonreaders a good idea of what the story is.
When you're done with the pictures, you can get to the text and listeners can have the pleasure of determining if that matches up with what they thought was going to happen as a result of looking at the pictures.
For authors reading to a largish group, I can imagine PowerPoint coming into play.
Thank You, Facebook
I learned about picture walks last night in a Facebook group I belong to. Don't let anyone try to tell you the Internet isn't wonderful.
