We have sibling issues. DS9 is clearly very gifted in math, moreso than his older brothers. DS13 is enough older that he doesn't feel threatened but definitely appreciates it and is sometimes wowed. Meanwhile DS11 has historically felt very threatened by it. I've had to ask teachers to keep DS9 a few lessons behind DS11 when they were in the same class. Now they're in different schools (till next year) and things have been peaceful. However, last night they were playing a great ThinkFun game called Math Dice, altogether with DS 6. DS 9 won almost every time and DS11 was a little fragile and teary. I have no real solutions--they're all amazing and brilliant in my eyes. We'll see what I can figure out for not getting in each others' way in jr high/HS.
