I made a lesson for my h.s boys on lying / dishonesty. I will teach this to my second grade students.
Part 1 (lesson 1) deals with lies, why we lie and the tell tale signs of lying. I know different psychologists say different things about lying signs, but I found the ones mentioned to be the most commonly spoken about (change at your own discretion) (this ppt was made by me, change it as you need to!)
Part 2 (lesson 2) Students will break up into groups and write a dialogue that deals with moments of honesty. (this w/s was given to me)
