This idea came from my sister. She read some informative and creative books with the boys. The fictional ones were: "Baby Brains and Robomom" by Simon James, "Rolie Polie Olie" by William Joyce, and "The Robot and the Bluebird" by David Lucas. Then the built their own robots! They used egg cartons, pipe cleaners, beads and stickers. They loved it and their imaginations were running wild! What a fun preschool day!
