I don't think there are ways specifically for 8 year olds, what one needs is an 8 year old who is motivated enough to take the route that adults take. There's no material on topics like this to 'gamify' learning Blender that will trick kids who aren't sufficiently motivated in the first place into learning it. But if your point was 'he was asking about methods for 8 year olds so your answer is irrelevant to the question', then yeah, fair enough.
