I noticed one of our just-turned 3-year-olds (O.P.) quietly observing the class. He must've noticed that several children were wandering about the room, trying to choose an activity. He boldly stepped into the center of the classroom and announced:
"Now let's go people. Let's get to work!"
He then walked back over to his mat and continued the lesson he was working on. A few children noticed his announcement and took it quite seriously, moving to the shelves and finding work. Our oldest student looked at me with a smile, shrugged, and said "I guess we better work."
