"Come on, we're going to be late to transfiguration!"
"Calm down we're almost…damn."
"It moved again."
"I hate these first couple of weeks, the classrooms are always moving."
"This way."
"How do you know?"
"I cast a locator spell, come on!"

"We've been running forever, are we there yet?"
"Almost, we just…"
"That's a wall."
"I don't understand, its pointing right at this wall!"
"What spell are you using?"
"Four point spell."
"Four point spell! You imbecile, the four-point spell points north!"
"Oh."
Spell: four-point
Function: points north
Book: 4, Harry uses it to get to the center of the maze.
When to use: When you have to go north or some other cardinal direction.
When NOT to use: When you are trying to locate something that moves, or any time that knowing which way is north won't help.
AN: While the story I got this from did use the four point along with some other spells completely wrong they did realize that the classrooms migrate throughout the books (or else they went to JKR's site, which still shows dedication) so my hat is off to them.
