Math shelves are on the left, book rack (I love this thing so much - it was an awesome $10 craigslist score, but, honestly, the kids totally ignore the books in it! argh!), mirror and DIY mobile for Felix (which was quickly destroyed by Lucy), Lucy's shelves with practical life and sensorial works mostly on the right. The kitchen is up through that window, so in theory, some day, I can work in the kitchen and keep an eye on the kids diligently working independently.
Another angle on the math shelves, with our "learning basket" of read-alouds on top (we actually read these out to the couch, but they live in here), and a basket of work mats to the right. The schoolroom doubles as our home office, which is not recommended by Montessori-at-home experts, and, in fact, has proven to be a bit of a distraction.
Beyond Lucy's shelves are language materials.
This all worked great for a little while, but Felix is now quite mobile, so schoolroom times have been fairly chaotic of late - time to make some adjustments. The table also was too small for both big kids to work at simultaneously and really too small for Joseph generally, so it has been moved to Lucy's room, and I'm on the hunt for a replacement.
