I've been told many times that night court is some of the best free entertainment in town. Admittedly, I've dragged myself down to the audience benches more than once to get giggles watching the judge and a parade of police try to bring forth coherence from the drunk and disorderly.
Now, for those of us blessed (for lack of brutal honesty) with children, another amusing diversion is to push them to work their brains when they have little interest in doing so. Oh, such a fuss. Hey, they need to earn their keep. Entertaining you is the least they can do in your honor.
There are lots of ways to get those brain juices pumping and you may already have your favorites. What I propose here is to engage their critical processes to productive end. Whether using stories they're reading or movies they're seeing, get your brood to show off what they've got by articulating what they do and don't like about the work. Add to that by having them go into detail about specific elements that do or do not serve the story well. Push their imaginations by having them share anything they might have done to improve the story.
There are many things you can do with that, taking it from directed conversation, to an organized game, to full-on home schooling if you like. The important thing is that you have fun with it. Oh, and get those brains active, too.
