Sideways Stories from Wayside School kids novel by Louis Sachar 1995

GUC softcover The Wayside School was supposed to be one story high, with 30 classrooms side by side; instead, rooms were built atop each other - 30 stories tall. In 30 tales, meet meanest teacher Mrs Gorf, terrible Todd sent home early, John only reading upside down, Jason stuck to his seat by chewing gum. Some tales have a bit of a moral - Kathy assumes no one likes her.
