I guess I don't really understand the question since nobody teaches anything to childern. Breeding childern with high skill builder gives points in it to offspring. All chatting,arguing,teaching,complaining, etc is directed to the fist male in the game file. At the start of the game that would be the oldest male but after he dies it jumps somebody else to that slot who may not be the next oldest male. The game left on 1/2 with several people checked as builders should be able to make master builders. I think the game does a better job then a player would. In one game I had made a drastic mistake so I reloaded an older game file and took a different course. Wanting to check something out 5 or 6 days (perhaps even more)I reloaded the previous game file and saw I had left it to 1/2. Well of course all my elders had died off but oddly enough I had about 4 master builders in that game, odd since all that could be built was an idol that was 40% completed. Some of these new masters were only 10-8 years old when I had left. Just how they managed to master is beyond me. I replayed that game to find out and I sure couldn't pull of that many masters.
