When a substitute teacher named Miss Pelly comes to class, one student bristles at the change in routine -- Miss Pelly doesn't follow the rules like Mrs. Giordano. But in time, our student learns that even though the substitute may do things a little differently, and she may be a bit silly, mixing things up might not be so bad. Told in a series of epistolary poems, this funny, relatable picturebook is a great fit for classrooms and for any child nervous about new experiences.
