A Child's Touch

I am in the middle of reading Spaces and Places by Debbie Diller, one of my favorite authors (educationally, speaking). I spend lots of money on my classroom; I am constantly buying books, both professional and children's literature. As I read through Debbie's book last night I began to wonder if all the stuff I think needs to be in my classroom really needs to be there. So, I will spend the next few weeks rethinking what is essential and what can be given away. I want my classroom to be a place where children enjoy learning and are developing independence as learners. I want my classroom to have "a child's touch." What are your thoughts on what's essential in a classroom? I'd love to hear from you.
With a teacher's touch,
Linda
