I know it's a funny question because the obvious answer is home, but where in your home do your kids do their work?
I tried for years to make a school space. I even had a school room for one school year, but finally gave up because no matter what, the kids always ended up somewhere else.
It wasn't their fault either. There was always a good reason. Sometimes it was because the light was better elsewhere. Other times it was because I needed to be in another room, but the kids needed my help.
I've finally decided that we have a central place for school books and such and the kids can do their work wherever they land. Generally this is the kitchen table, but not always.
This is where I found them a couple days ago.
