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.
Computer is one of the requirements for a teacher and to the student (kids) because if they don't have computers and they are just like lecturing by writing and discussing without the actual process then it will be hard for the kids to understand how bitcoin actually work because they are lacking in actual experience.
