"As a scientist, Maria Montessori discovered something surprising:
When children are active participants,
when their choices are respected and guided, and
when responsibility is expected and nurtured,
a new child emerges.
This child’s characteristics are concentration, self-discipline, love of learning and a respect for others and the world.
This child is our best hope for the future.
Share the hope.  Experience the surprise.
 Visit a Montessori school today."
