Talk to your children about how they can be a peacemaker. Ask them about times that they got angry, mad, etc and someone helped them calm down. Then ask them if they would like to be a peacemaker. Talk to your children about great leaders that taught peace (Martin Luther King, Ghandi, etc) Tell them how their practices of peace accomplished much more than they could have by fighting. Make a large bulletin board cloud on a piece of paper. Then ask your children what their dreams are (what they want to be when they grow up, ways to make the world happier, etc) and write them in the cloud.
