Somewhere between 1st and 3rd grade I remember being read a book series. Sadly, my memory of it is vague. But I'd really like to get a name, so I'll say all that I remember...

All I really remember about the book is that it took place in a school, but the main characters in the school weren't in a normal class. They were either on a half floor(like Floor 5 1/2) or on a floor that the rest of the school didn't know existed. Their teacher was eccentric and fun. I don't remember any of the characters names. That's all I really got

Oh, and it's NOT The Magic School Bus. Just getting that out of the way now.

Was it the Wayside School series? It was about a school that was built sideways and it was missing the 19th floor. I read those around the same grade, the only thing I remember was in one chapter the janitor had to carry a heavy computer up the stairs to the top floor. Then the teacher threw it out the window to demonstrate gravity, if that's not eccentric nothing is.

Yeah!! That's it!!
Thanks

Oh i loved that show. I wish it wasnt cancelled
