Deeply buried in Education theory is it's discouraged to have
  students go to their parents for help, as the parents will have
  inferior knowledge than the teachers. The shell game continues
  as new methodologies have to remain a few steps ahead of things
  parents can help with. Once Sylvian learning center has new
  shortcuts to teach kids regarding this style of math, something
  else will come along. More ways for school to suck. Amazing we
  make it through. Maybe they know something, I dunno... I just
  hope so.
