It seems that young children love nonfiction books, but quality nonfiction books for preschoolers and toddlers are hard to come by. That is why I was thrilled to find a great nonfiction moon book at the library. It is so new that Amazon doesn't have a picture. It is short, informative, and interesting. The book is Space Watch: The Moon by Chris Oxlode.
In the final section there is moon phase matching to night sky pictures. Ladybug and Mister love to match the pictures, so I made our own set. It took a few attempts to find good night sky photos, but I found an informative moon site with good pictures. On the back of the cards, there are colored dots for the cards that match.
