Lead your class in brainstorming the idea of kindness. What are some examples of kind behavior that they can list? Write down the examples on a kindness chart that's either a large piece of paper or white board, clustering them with similar concepts. For example, "sharing your toys" might go next to "bringing in treats for the class."
Divide the class into small groups and have each group create an art project depicting an example of kindness from your kindness chart. Encourage the students to work together and show each other kindness as they create the art project. The project can be a picture, a mosaic or a sculpture -- use your discretion and whatever supplies you have on hand.
Allow each group a turn to explain its art project, what it depicts and why it is an important component of kindness. Display the art projects, along with an explanation of each one, for the entire class and any parents or visitors to see.
Ask each child to describe a time in which someone was kind to him and express feelings for that person. Explain that he will be making a sweet treat for the person who was kind to him in order to show his appreciation.
Distribute a cookie to each child in the class. Help the children decorate their cookies using icing, sprinkles and whatever other edible decorations you have selected. You may want to have extra cookies on hand in case of cookie-related mistakes such as "accidental" eating.
Encourage the children to decorate a small paper bag to hold the cookie using crayons, stickers and other art supplies you wish as the cookies dry. Place each cookie in its bag, fold over the top, punch a hole with the hole punch and tie a ribbon through it.
Send the children home with their cookies ready to be distributed to the cookie recipients. Encourage them to explain to their cookie recipient why she is receiving a cookie and to express gratitude for the kind behavior that she exhibited.
Revisit the project the next day in class. Have each child tell the story of how he gave his chosen recipient his cookie and how it felt to express kindness in this way. Ask: Did the recipient like her cookie? Did it feel good to give her the cookie?
