I always tell my students (pre-k throught 8th) at the start of the year that
when they enter the art room they become "artists". They have to think like
artists, act like artists, and treat the art room and the materials like
artists. When one of them does not behave like an artist, I remind them of the
fact and that perhaps they need to step out of the room till they get their
mind set back into an artist one. Some are so cute about it, and as they walk
through the threshold announce to the others that they are now "artists".
All the best--DeDe
