For prediction and making mental images, I love "Just an Ordinary Day" by Rod Clement. I cover the outside of the book and read it to the kids so they can't see the illustrations. We stop at certain pages, and think about what we see--sometimes a turn and talk, sometimes a quick draw of what something in the story looks like.
After the story is over, we share ideas and illustrations. Then I remove the cover and show them the real illustrations, which always surprise everyone!!
