I think in teaching kids about bitcoin, you should start with a basic.But I believe that computers has a big help for the learning of the kids about bitcoin.Wherein they can create an application regarding the teaching of bitcoin for the kids.
No need to create an application at all since you can simply read about bitcoin online. After all, the application that they are going to create will also have explanations in texts form. Or if you want some visual explanation, then you can watch it on Youtube.
Kids are totally good at computers, but that doesn't mean that they are going to learn about bitcoins easily. Most kids are only good at computers because
they always play game on it. The area of their expertise is limited on that and technical stuffs like bitcoin which requires basic knowledge about math/economics will not be learned right away.
I am not quite sure that kids nowadays are only limited to playing video games. I saw kids involved in modding, coding/programming, YouTube-ing, streaming, earning money online, developing websites, etc. Kids' minds are much more open than ours as they get to use computers and Internet while they are still crawling.
But sure, I will teach my kids about Bitcoin, and how great such a technology is.
