Don't force your kids to do math 1 year ago
I would agree. Kumon wasn't my son's favorite thing and he eventually decided/asked to stop. But the repetition and discipline of working at it every day had an influence. It didn't manifest until undergraduate but he ended up switching majors to math and is now pursuing a math PhD. Probably not common, but like learning to play the piano, I think it gave him a comfort with the basics and an intuition that allowed him to explore his own interests.
