It might be difficult to imagine what world peace actually looks like, but young children have vivid imaginations. Have your students draw a picture of world peace. Give them a sheet of paper and let them use crayons, colored pencils or water-colored paints. You don't need to give them instructions beyond this. Try playing soothing music in the background as children draw and paint. At the end of the activity, ask students to tell the rest of the class what their pictures contain and how they relate to world peace.
Children can get a better sense of conflict and peace if they can imagine someone their own age in a non-peaceful situation. Have a short discussion about one conflict or war in the world. Explain in simple terms what is going on and how it affects non-military citizens, including children. Have your students write a letter to a child affected by the situation. If you have students who are too young to write by themselves, write the letter as a class or ask for parent volunteers to help the students put their ideas down on paper.
History is full of inspiring people who have tried to stop war and promote world peace. Teach your students about one such figure, be it Gandhi, the Dalai Lama or John Lennon. Tell your kids about what that person did to promote peace in the world and put an end to wars. Then, have children imagine what they would do to stop war if they could. Let them write it down in one sentence and make a poster illustrating the idea.
One way to teach children about world peace is to make it local. Peace starts in the classroom, and teaching students the importance of working together and being nice to each other promotes peace in the world. Ask your young students what it means to be peaceful in the classroom. Ask them for examples of peaceful acts, such as apologizing, sharing and helping out someone in need. Have a supply of stickers that you can give out whenever a student does one of these acts.
