This is a great way to teach children to move and defend themselves in a game way. Give two kids a jump rope or a long belt and each one holds one end. Now they try to loop it around the others neck (without giving it too much pull) as the other moves first with just the body and neck and than with the hand that is free and than with everything. you can also have a two on one where one kid holds two rope ends and two other kids work with him and so on. Adults can do this too with the same effect and move later on to the chain which is less kid friendly.
