Hello, I have a couple of questions to answer and then I would answer yours.
- First things first. Does the school approve of what you're teaching to your students? Teaching blockchain, smart contracts and Bitcoin are something that even computer science departments in higher education don't do. Curious to kniw the circumstances surrounding your teachings.
- Do your maths students have prior dev experience before going off to learning how to create tokens?
As for your question, there are plenty of things about Bitcoin (if it's allowed in the school) that doesn't necessarily involve development activities or everyone to have a phone. You can just teaching them the theories and concept of bitcoin and open finance. There's more than enough topics to cover.
The school has no issue with me teaching anything blockchain-related. I had already taken that up with my bosses before attempting. Remember this is only for a total of 2-3 days over the entire school year.
My students certainly do not have any dev experience outside of using coding dot com. As far as "just teaching them the theories and concepts of bitcoin", theories and concepts do not make for a very exciting project. Especially the day before Christmas break.
