I’m kind of with you on this, Mrs. B. My kids would probably give me funny looks if I set aside one specific “school” room/area. Of course, if we had a different house with a spot for it, I’d probably designate a room with a table or two for seatwork and projects that need that kind of space, but right now we just use the kitchen table. When I have to separate them for whatever reason, we also use a portion of the dining room table and a small folding table (like a tv tray table) in the living room. My oldest likes to read her literature and history in her room. For read alouds, it’s either gathered around the kitchen table with lunch or in comfy spots in the living room.
We do have a spot for the computer and a file sorter to keep papers and things “in progress” plus a tall, 2-door cabinet for books and some supplies. The cabinet used to be set up with a separate shelf for each of the three children, but now that we combine some subjects, they just know which section has their books vs. the family books.
