Our method is to allow the children to create the environment. Sure, I have some personal things adorning a few areas. But, on the whole, the classroom is a shared environment for both the teacher and students. At first, this seemed preposterous to me, and for years I fought it tooth and nail. But now? Well, it makes sense. A learning classroom and a perfectly appointed classroom are not the same.
So, though the walls and bulletin boards are blank now, don't you worry. By Thanksgiving, we'll have every once of wall covered with the students products.
And, I'm sure that you're tired of hearing about school. But, that's what my life is revolving around right now.
