Many people told me, it is very important to get a good piano teacher from beginning, some teachers just had no experince for talent student, like ours.
I went to students piano ratical yesterday, one of 9 yeard old boy display very high level technique skill which at least grade 8 or higher, his mom told me they have changed a few teachers until they found the right one, then her son toke off in just a few years.
Funny thing is, this boy played whole music without looking any notes, he must had expentional memory too.
For math...I rather play numbers game with my son,get him idea the connection and pattern of the numbers,try to sole a math problems with different ways even a very simple one, it will help the math ability in long run.
