One of the bizarre things about unschooling is that the other day, when some of them earned some money, I was discussing ma'aser and asking them what 10% of their earnings would be, and they all got quiet and started thinking about it.
They all had ideas about how to approach the calculation and they all knew something about percents. How? I'm not sure. It comes up.
And the other day, my youngest was staring at the clock and he explained to me a rather long and complicated process for telling the minute hand on analog. He said if you add a zero to the number and then divide it in half, that's the minutes. I did a few and sure enough, he was correct.
I find that with unschooling and with them playing all day and having the kind of slow paced life where there is time to daydream and they have unlimited video games and youtube, they end up pondering mathematical concepts in a way you just never have the time nor inclination to do with standard education.
