Never before has a school been this mixed up - or this much fun! A.J. and his friends aren't sure what to make of their crazy school. Their teacher can't read or do math, the principal paints his bald head orange, the librarian believes she is different characters from books, and the school nurse may be an international spy. Each book focuses on a different staff member of a typical elementary school. By Dan Gutman. 96 pages. Reading level 2.5-3.5 Interest level 2-4.
