Congratulations. Your children are clearly knowledgeable and sophisticated users of technology.

Most kids don't get that far. They don't have parents like you (or me) to give them one to one help and encouragement.

Thats the point. Start with simple, concrete stuff. Work up to the complicated, abstract stuff. Basic pedagogy. Raspberry Pis undoubtedly have their place, but they're less than ideal teaching platforms if your aim is to get children interested and enthusiastic about tech, rather than simply being "users".

(As for future proof skills, I suspect you know as well as I do that nothing ever is - as the absence of BBC Model Bs in todays classrooms demonstrates.)
