'Not a Box' by Antoinette Portis is one of my favorite books to use in my classroom! It is such a simple book but it sparks such creativity in the children and aligns very well with the Trait of Ideas from the Six Traits of Writing. We created our own class book about what we might do with a cardboard box. Below there is also a slideshow of the children playing with a cardboard box and their peers are guessing what they could be. Can you guess what we are pretending to do or be with the box?
