<p>As the parent of a D who is mathematically gifted but dropped math many times for social reasons, I can tell you that there are all sorts of societal reasons girls in the aggregate don’t do as well at math as boys. </p>
<p>When my own mathematically talented D was three, I found out that she never touched the blocks in nursery school. I was stunned. So, I asked her why. At first, she lied. She said she didn’t like blocks. I said that wasn’t true–she played with blocks all the time at home. Then she said "I want to play with the other girls. They don’t want to play with blocks, so I don’t. " She was THREE!!!</p>
<p>In kindergarten, there was another little girl who liked blocks too. So, they made a deal. At a certain time one day, they went into the block corner together. The boys started in on them, but there were two of them. So, the boys said things about “cooties” and left. After about an hour or so, the girls left the area, and the boys surged back in. The next day, at exactly the same time, the 2 girls went back in. The boys came out. Every day, they did it. On the 4th or 5th day, another girl joined them. By the end of the year, all the girls played blocks and the boys knew that hour was the girls’ time. </p>
<p>It was interesting that the girls played differently with the blocks. While the boys tended to co-operate to build the highest possible structures, the girls built things horizontally. Their very favorite thing was creating a really complicated maze and letting the classroom gerbil run through it, trying to figure it out. That intrigued a few of the boys, who braved social ostracism to contribute.</p>
<p>This is an absolutely true story…and I assure you that the girls in that kindergarten class were unusually good at math throughout elementary school. But if my own D hadn’t found out that other little girl liked to play blocks too, she never would have braved the boys alone. </p>
<p>I’m not claiming that girls in the aggregate are as good at math as boys in the aggregate–they aren’t. But a lot of little girls who might be good at math are dissuaded from following their interest because they want to fit in socially. And math is one of those abilities that develops more if it’s fostered at a very young age. Even by age 3 or 4, little kids tend to segregate by sex when playing and most will do what the majority of the same sex want to do. It’s hard to buck the trend…and IMO, we ought to give kids more help doing it.</p>
