A classroom with Baldi's Math Machine and some number balloons.
Classrooms are rooms placed around the Schoolhouse and Super Schoolhouse. Every classroom has a teacher's desk, wooden seats, blue carpet flooring, a chalkboard with something written on it, possible items on some of the tables, possible papers and an uncollectible notebook objects, and a collectible notebook on the big desk the player can collect. All classrooms have at least one class door with the number 99 on them and some classrooms can have more than one door. In floor 2 and 3, all classrooms contain number balloons and Baldi's Math Machine instead of a stray notebook or a teacher's desk. The player must insert the correct number balloon into Baldi's Math Machine to get a notebook this way.
Overview
Main gameplay
A different amount of classrooms can generate depending on the floor:
Occasionally, the player will be chased into a room by Baldi but may escape by mimicking the opposite of his movement path, effectively running around him to escape. This will set the player in close quarters with Baldi for a time, making them vulnerable until breaking out of his range of chase. Another way to escape this situation is answering the math problem correctly on Baldi's Math Machine if the classroom has one, which results in Baldi being delighted for five seconds, allowing the player to escape easily.
Principal of the Thing will occasionally survey classrooms on patrol for suspicious activity. However, he will not pose a threat to the player unless they are breaking the school rules.
It's a Bully will sometimes block a classroom from being entered, depending on the tile of any hallway he is on.
Chalkles will spawn in some classrooms, slowly starting from the chalkboard. Once Chalkles becomes fully solid, he will fly out of the chalkboard, laughing to get Baldi's attention and locking the door(s) for 15 seconds.
Mrs. Pomp will invite the player to a random classroom once she spots them. The map shows her classroom until the player enters the room or the timer runs out.
Some classrooms can also contain two doors which can lead to hallways, another classroom, or other locations.
Rarely in floor 2 and 3, L-shaped classrooms will be generated.
In Baldi's Basics Classic Remastered, there are the same classrooms in Classic and Birthday Bash, but with different chalkboard writings, random-colored notebooks. The room materials in the "Math" classroom have been removed. In Demo Style, the desks are replaced with Baldi's Math Machines and items are randomized.
This is a list for all defaulted rooms. In Hide-and-Seek, Explorer Mode, Endless Mode - Random, each classroom comes with a pre-set string of items and objects that are selected randomly.
Every classroom has roughly 8-10 desks facing one wider desk (assumed to be the tables and big desks, likewise). They are arranged differently in different rooms, and one even has them all flipped over.
The only classroom that has two items is one of the classrooms in Endless Mode - Medium.
Baldi, Principal of the Thing, Mrs. Pomp and Dr. Reflex are the only characters that can enter classrooms while passive.
A tiny classroom.
Prior to V0.4, a tiny classroom could be generated. These rooms did not contain any furniture if they had a Baldi's Math Machine. Also, some classrooms did not have a Baldi's Math Machine in floor 2 and 3.
Baldi's Basics Classic/Birthday Bash
The "Geology" classroom has way more desks than the other classrooms.
Baldi's Basics Classic
Prior to V1.2, in some classrooms, chairs were floating above the ground.
Prior to V1.3, the Safety Scissors items were absent.
Prior to V1.3.1, Playtime could also be passive while entering, but this was changed.
Prior to V1.4.3, the Big Ol' Boots was not found in the "History" classroom as it was not implemented.
