The artwork is simple and easy to understand. I liked the Book Series because it showed the purpose of all parts being talked about to the children. A lot of color was used to point to different points of the book one might want to talk about with the children. Gail Gibbons is very precise in her drawings. I am working with 7 year old twins who are interested in various topics or items seen in stories, like what's the red object in the story 'The Garden that We Grew', in the Series of Plants.
