In 1st through 4th grade the teachers that were able to identify my giftedness really pushed my reading. I was placed in higher grades for reading class and books. I was never exposed to math though. So I don't think it could have been identified. I found that as I got older though I was very good at math, despite not liking it very much. I do believe if I was exposed to it at an earlier age that it would have been advanced development. In my experience alone I would think that just early exposure to math is unusual, not a gifted child being advanced enough to grasp it and run with it.
