Your situation sounds very similar to mine, OP. I have two DC close in age so I ordered two of the same desks from target, desk organizers and desk lamp to make it cozy. They also have this art cart to keep all their art items in

I think a mistake I made in the spring was letting DD get to choose wherever she worked from- and sometimes this was her bed. I’m planning on making their desk area the school area and having them keep their computers on theit desk and charging so we don’t have unplugged computers with no battery when we need them. Maybe I’m overly ambitious but I’m hoping to run a tighter ship in the fall (while acknowledging that it’ll Still be okay if we forget a few class meetings or slip up on some things)!
I’m also planning on looking up some workbooks and other items to supplement learning such as manipulatives for my kindergartener.
Any good recommendations for teacher supply stores available to the public?
