I think it's best to start close to the goal and move into problem-solving once something is up and running and needs improvement or optimization. Focusing on CS fundamentals isn't always worthwhile, unless there's a genuine interest in computer science or math olympiad style problems. Today, we can operate at a higher level since most core algorithms are already available in libraries and frameworks.
Just my two cents: if your kids aren't very interested or ready for that kind of knowledge now, you might find that in a few years they can learn it surprisingly quickly if they're interested then. What takes months to teach early on might work in days or hours later.
