This is a great activity for stories that have illustrations as a major component of the story. Eric Carle books are great to use for this activity. Being a blind illustrator means the students are read a story without seeing the pictures. Then, after they listened to the story, they illustrate it. The teacher should provide information about what illustrations are on each page. For example, if there was a one-story house with red shutters and a chimney with smoke coming out of it, and a pine tree on each side, the teacher would say "There is a house and two trees in the picture." That way, the student makes it possibly a different color, makes no chimney, or makes it a two story house, and draws two apple trees, making for a very different but (at the same time) similar illustration.
After the illustrations are complete, the book is re-read and the illustrations are shown. This way, the students can compare how their illustrations differ from the published copy. Although it should be pointed out that published books are from professional illustrators, there are still differences of how people view ideas in their own heads.
In terms of Eric Carle, this activity can show how much actually goes into making illustrations, and how difficult it can be. It also provides a great opportunity to see how illustrators might feel when they are presented a story.
