Give students a very lightly copied peace sign on paper. Allow them to transform the shape or fill in with reminders of peace...

Other idea...
Fold computer paper in half. Place hand on paper with thumb and pointer finger on the fold (slightly over). Trace hand. Cut along traced lines especially avoiding cutting on fold (where pointer and thumb tips were). Unfold paper. See heart? Glue down on contrasting colored paper and design!
