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 teach them the theories and concept of bitcoin and open finance. There's more than enough topics to cover.
