They're going like gang busters to try to each every kid how to code. I've suggested they focus on number systems like base 2, base 8, base 16. If they can handle that then you start with Boolean logic. Then open source software - python for example. It's a simple but very powerful language.
That Boolean thing is clutch though - once you understand that you're pretty much good to go. And of course some critical thinking is in order too.
