Well, if you want to play school with them take turns being the teacher. If your daughter can read let her read you and the friend a story then let her make up quiestions about the story. Let the friend be the teacher next and teach you and the daughter how to do a craft she knows how to do. Is the girl there for a playdate, or babysitting? Instead of you playing the teacher and them the students give them each their own "class" of dolls and bears. Let them select an activity from the learning shelf and teach it to their dolls. Think, think, think (tapping my head like pooh bear). Nope, out of ideas.
