My son been to pre-school nearly a year, and today, pre-school teacher just told me how shocked she was when she found how advanced DS4 is, even she knew he loves numbers, time, calender..etc, but last week, DS 4 was talking squre root totally amazed her.

I think the teachers had not much experince with kind of gifted children expecially come with math, and she told me DS was bit slow thinking and has hearing problem when he just entered pre-school, while he was already reading, knew mutipulcation ,divison etc
