Last fall, I was in a second grade classroom, and we did a short author study on Mo Willems. The students already knew many of his books, especially the Pigeon books. I introduced them to some they did not know as well like Leonardo the Terrible Monster. We discussed how Mo Willems is also an illustrator but has not illustrated all of his books such as City Dog, Country Frog. If you have never visited Mo Willem's website (http://www.mowillems.com/), you need to. One of my friends and I also made a bulletin board to go along with this author study.
My favorite Mo Willem's books are his Elephant and Piggie books. I have been reading one of these with my 6-year-old cousin each time I see her, and we love them. They are hysterical! My favorite is We Are in a Book!, where Piggie explains to Gerald how they are in a book and can make the readers say things. At the end, they ask the reader to read it again, and my cousin always wants to in order to make them happy. As a beginning reader, my cousin often has a hard time focusing on reading, even though she loves reading, when there are too many words or when she is overwhelmed at the length of the book. I found that these books were perfect for her. There are few words per page, and it repeats the same words throughout the book. It is also nice that there are usually two parts, so she can decide which character she wants to read for, and I can read the other. The text is so engaging we want to read them over and over again. Mo Willems is an author that children definitely love.
