Great teachers are always on alert for teachable moments that will engage kids in new learnings. Yesterday we were presented with a teachable life in the form of the truly extraordinary hero to many:Nelson Mandela. I am deeply sadden by the passing of this moral global force. But I am also hugely impressed and pleased by the universal celebration of his life and incredible contributions to our moral center.  His is a story and example that every student every where should study and learn from. Indeed Mandela is a teachable life for the ages!
