Is there a term to describe when students are in one classroom for most of the day? When I was in elementary school, I was in a single classroom the entire day. I would have different teachers come in and give classes, but we as students wouldn't change our classroom. When I was in high school, we were in two classrooms, first half and second half of the day. 

There seems to be a term for every single possible classroom arrangement, but I haven't found one for this. I've seen it once called "Homeroom," but the Internet seems to disagree (https://en.wikipedia.org/wiki/Homeroom amongst other places). Any suggestions? 

Additional context: The company I'm working for is building a school software so terminology is critical when initially setting up courses/classrooms etc. We've spent a ton of time researching terminology, but this one has us completely stuck.
Something close may be a “floating teacher model”.

A room is predominantly occupied by one instructor then another comes in during the primary instructor’s prep period to teach his or her lesson.  There’s no reason one room would be restricted to only two teachers in this practice. “Cart” teachers or “mobile” teachers are also commonly used terms for these roles. While there is research on this practice, I haven’t come across any where all teachers are subject to moving between rooms. That’s not to say a universal term for the structure does not exist.
