A picture really does tell a story.  This one tells us about the Grace and Courtesy curriculum in Montessori schools. We can see that the children are waiting in line.  That the line has moved ahead is clear. That the two girls are focused on something in one of their hands and have not noticed the line has gone is also clear. That though he even appears slightly annoyed the child in the green jacket has not resorted to a physical response.  He is using his words to tell them of the line movement. Peaceful resolution. This is the goal we work toward daily in Montessori schools. Learning how to be in community together is foundational work to which Montessori educators pay critical attention.
