This year's Great Kindness Challenge, the 4th annual celebration, reached as many as 69 countries, based on website data and firsthand accounts.

On this special day, children around the world performed countless acts of kindness. Guided by our 50-item checklist, they spread joy with smiles, hugs, dances, and thank yous. They brightened many days with hand-made cards, drawings, signs and painted rocks. They served their communities by helping those in need, cleaning up the environment and caring for pets. In short, they made a big, positive difference in in our world, and changed many lives for the better.

The 2011 Great Kindness Challenge was sponsored by generationOn and Southwest Airlines, with public relations support from CRT/tanaka and web design services donated by Envisager Studio.
