Next Friday, I am having my kindergarten meet n greet where my students and parents come the Friday before school to meet me and each other. I have out little activities they can do and I let them explore around the classroom (blocks, playdough, home center...simple things). I work at a small school so I have a small class. I will only have two boys and the rest will be girls. I know that when the students trickle in to see the classroom, all of the girls will want to play in the home center where I have a little kitchen, crib, table, refrigerator with play food. I can't have all of them in there at once. How should I go about explaining that only three can by in there at a time when school hasn't officially started yet?
