My 7 year old niece is OBSESSED with playing school. Over Thanksgiving break, I brought her up to work and let her play in one of our empty offices. She loved having her name on the door (she made her own sign), having her own phone (that I unplugged), her own rolling chair, desk and white board. I even made her a mock badge like the one I use to turn my computer on and open doors in my building. She was in heaven.
