Put paint on the plates and place them on the craft table.
Ask the children to draw a peace symbol with a pencil.
Then ask them to decorate this peace symbol with paint.
You can also do this craft together with several children, each of them being assigned to a specific colour. For example, in a team of 4, child 1 will put the red paint on all symbols, child 2, blue paint, child 3 green ones and child 4 yellows. Finally, the 4 children worked on the 4 crafts.
