Teaching Values in the Preschool Classroom

What values do you teach your children? Some peole teach rights. Some model rebellion. Most believe in altruism. Are we teaching that? Traditionally duty was taught, but today our culture seldom mentions that.
I submit that if we teach only rights and never duty or altruism, we may have an unpleasant culture not many years hence.
Anyone have good ideas for teaching altruism?
