21 days of Kindness Challenge activity is based on the idea that habits are formed by repeating an act for 21 consecutive days. The activity will help in fostering the culture of Kindness in the classroom. One random act of Kindness can create an endless ripple and only Kindness has the power to transform the world. As Aesop, the Greek storyteller says "No act of Kindness, no matter how small is ever wasted".
