Preschool Classroom Designs

I've decided to teach Preschool this summer at Ready-Set-Grow, our Preschool and Childcare Center.  We have over 75 students, but only about 25 preschoolers.  Sooooo. I have been looking at preschool classroom designs and ran into these.  I have a huge room and so I want to put a large reading center (book nook) in an area.  These classroom designs are brought to us at the Modern Architecture Decorating Ideas Directory Blog:
