I just recieved this in an email and thought it would be good to share. Here is the link for a few more tips also, http://powerofmoms.com/articles/228/1/Monthly-Value-July-The-Value-of-Honesty/Page1.html
This is a motivational way to get children to evaluate their personal honesty every week. On Sundays (or whatever day you most often get your whole family together for a meal) ask, "Who had a situation this past week where it was a challenge to be honest?" Have an "award" on hand to give to the person who remembers the best incident of being honest. A piece of construction paper or colored card with a neatly printed H.U.P. (Honesty Under Pressure) will do nicely as the award. Let the child (or adult) who wins put it on his bedroom door during the week until it is awarded again the next week. After a couple of weeks of "getting used to," you will find that children are thinking hard about their behavior of the past week in hopes of winning the award. And it is this kind of thinking and recognition that strongly reinforces honesty.
