Making art with kids is one way to get them thinking about harmony on the playground as well as peace in the world. Don't worry if you never earned your own Banner-Making Badge—noncrafty types can borrow ideas from an online YouTube tutorial or a 3D lesson to teach kids how to fold origami paper cranes (remember International Day of Peace on September 21) or make a peace calendar using this lesson from the web site TeachPeaceNow.org.
