This includes directions and a rubric. I use it with the story "Lamb to the Slaughter" for 9th graders, but it could be easily used for other grade levels. It really helped the kids understand the different kinds of irony because they had to use them in their skits, and they didn't want to be wrong. After they perform their skits, they have to tell (or sometimes I have the other kids tell me) what happened in the story that was each different kind of irony.
