A picture book classic from mom-and-daughter creators Anne and Lizzy Rockwell—helping kids begin to explore careers. On Career Day the children in Mrs. Madoff's class take turns introducing special visitors. Every visitor has something interesting to share, and together the class learns all about the different work people do, from writing books, to working in construction to being a veterinarian. In the fourth Mrs. Madoff book, Anne and Lizzy Rockwell revisit Mrs. Madoff's class as they help young readers explore the question "What do you want to be when you grow up?"
