My daughter’s favorite book right now is Inside Outside Upside Down by Stan and Jan Berenstein. It’s a cute book from the Dr. Seuss family. Even though she is only 3 she can pretty much read the book on her own now by just looking at the pictures.

Brother Bear gets into a box. Papa Bear turns the box upside down, takes it outside, and puts it on a truck. The simple art and rhyming text make this a perfect choice for teaching spatial concepts.
