Interesting article. We always assumed that DS6 was gifted in math. I guess a child who uses abacus to count how many arms 6 octopuses have at the age of 2 is likely to be pretty good in math. DS6 read chapter books at the age of 3 and I must admit that at that point his reading seemed much more off the charts than his math knowledge. That said we always saw him as a math kid perhaps because we could appreciate his logical thinking or perhaps because we fully expected him to be one. Dh, BIL, FIL and I are all quite gt in math and I must admit that we expected our children to be good at math. He was always VERY logical. There are lots of math moments which stand out like learning a binary system in a museum in 15 minutes at the age of 4. To us he was always a math kid.
DS4 is a different story. He has been more verbal than his older brother at pretty much any age. He started reading at 2, he was better in puzzles but he was never better in math than his older brother. His math has been coming along lately and he does know a lot. I have no doubt that he too will be very, very good in math but I don't think he will be such an extreme as DS6. We call him our engineer and I believe that's who he is. He can see things in different light, he has the right imagination but he doesn't have DS6 extreme logic. I may be wrong and DS4 may be better than DS6 in math in few years but I doubt it. We will see.
