This is The Friendship Path we have at Lander. I developed this path for children to use when they have a conflict. Each child stands at opposite ends of the path facing each other. The child with the first birthday in the year goes first. Each child takes turns completing the sentences as they walk toward each other. In the middle, they shake hands if they feel the problem in solved. If they do not feel it is resolved, they try it again. If after the second try, they cannot agree, they can write a note to me so I can help them solve their problem.
This can be used at home for sibling conflicts as well. Simply write the words on a large sheet of paper or just have the children do the path orally instead of actually "walking" through the steps.
Check out the Friendship Path for kindergarteners and early readers, too!
