Helping on peer mediation

On Tuesday I did peer mediation with Rebecca well actually filled in for people. We were on the junior school and we had a problem the issues were the people playing were arguing over the game,people leaving each other out,and the rules of the game not being explained. We were solving the problem for the whole time we were on and finally we came up with a solution for them. Rebecca and I would make them a treaty of the game rules so we quickly wrote down the rules and got them to all sign it and then they were all happy to play they couldn't wait to till they could play again.
