Yes- elementary (k-5) and middle school (6-8)were like this, although with minor variations.
Both school buildings must have been designed by the same architect and built by the same contractors- they had the same bricks, same basic design, same carpet, same tile, same fixtures, and so on and so forth.
The elementary school was arranged with each grade level (ideally) arranged as 4 classrooms in a large square room with blackboards in the outer sides, doors in the top and bottom center, and windows in the left and right centers. Classrooms were partitioned off by rolling cabinets, bookcases and coat racks. The classes were organized by grade level however.
Middle school had each set of 4 classrooms aligned in a row, with pull-out dividers that could separate the classrooms. The beginning and end classrooms had their own doorways, but the middle two shared a large doorway.
This sort of made sense for middle school; the teachers and students were also organized into pods as well- every 100 or so students in each grade was organized into a pod, where all had the same English, Social Studies, Science and Math teacher, and were slotted into one of 4 skill levels basically. Gifted students (and special ed, I assume) were members of a pod, but attended classes outside their pod for the gifted classes, and only were part of the pod for administrative and their non-gifted classes like social studies, and in my case, math. Other students were in the gifted math classes, but not English, for example.
High school on the other hand, was straight up classrooms with walls between them. A few had dividers, but they were always pulled shut, and there was no administrative concept of a pod.
