With Eric Carle quality pictures, this book by Bill Martin Jr. is full of colors and animals for little people.
no actions (besides seeing)
We checked this board book out from the library. My first grader easily read it and suggested that his little brother and sister read it, and it was short enough that they sat there for the whole thing. I always enjoy Eric Carle's pictures and Martin is creative with how he colors different animals. On each page an animal (or at the end, people) tell us what they see, that we then see on the next page.
