I have introduced several local kids besides my own, to basic marksmanship, started them with iron sights mostly because they were poor and shooting old family single shots and didn't have a choice of scopes. I actually took pencil and paper and sketched for them the difference between sight alignment and sight picture and explained how sight alignment was critical. The 9 or 10 yr olds grasp the idea quickly. I think learning irons helps them later if they graduate to handguns. The ease of scope use gratifies the mentor with quick results but I'm not sure you are doing the kid any favors. Start your kid on a manual transmission and he can drive anything easily before he is 16, IMO.
Trust me my kids will drive manual comfortably or not be allowed to get their license
