Some schools in Connecticut and elsewhere around the country are performing 26 acts of kindness as a way to honor the victims of the Sandy Hook Elementary School shootings.

It was nearly three years ago when a gunman shot his way into the school and gunned down 20 children and six educators.

At Pleasant Valley Elementary School in South Windsor, Connecticut, students are writing their good deeds on slips of paper on a hallway wall. Principal Tiffany Caouette (koh-EHT') says most students have no knowledge of the tragedy. For now, she said, it's simply important for children to know they are doing something good for somebody else.

In the aftermath of shooting on Dec. 14, 2012, people took to social media to promote the idea of doing 26 acts of kindness to celebrate the lives of the victims.
