Ingenuity
My 2 1/2 year old son really likes Maisy. Maisy is a cartoon mouse and the star of a series of childrens books and videos. One of her friends is an elephant named Eddie and although he and Maisy are much closer to the same size than they would be in real life, Eddie is still significantly bigger. My son was looking at a book that showed Eddie and Maisy outside Maisy's house and he said, "Eddie's too big to get into Maisy's house." So I asked him if there was any way that Maisy could get Eddie the elephant into the house. He thought for a minute and then said, very somberly, "A hammer."
