Sideways Stories from Wayside School

The story takes place in the fictional Wayside School, a school that was meant to be built one story tall with thirty classrooms all in a row, but was instead built thirty stories tall with a single classroom on each floor, save for the nonexistent nineteenth story. The book is primarily set in Mrs. Jewls' class, which is located on the thirtieth story of Wayside School, and each chapter focuses on a different student or teacher at the school.
