Need Suggestions For Fun Ways To Teach Toddler Discipline To Parents

I am instructing a parenting workshop for a class of mine next week. I have to come up with creative/fun ways to teach these parents how to properly discipline their toddlers. We already have all the necessary information for the workshop (i.e. remain calm, provide consistency, positive reinforcement, etc.) but we are struggling with ideas on how to incorporate a fun and interactive way to teach the parents these tips, rather than providing a boring lecture. Does anyone have any suggestions? They would be greatly appreciated and so helpful for us! Thank you!!
