When a violent shootout erupted last week in Monterrey, Mexico, kindergarten teacher Martha Rivera took quick and decisive action. She told her class to hunker down on the ground, and to keep the children calm she offered them chocolate and cheerfully sang a Barney song! Video of the incident is remarkable, as it shows just how composed she remained despite the danger that was raging just beyond her classroom window.
It's no wonder she was honored for her courage. Watch a video report, including a clip of the incident, below:
