My kids knew from a very young age that their mom and I were way smarter than any teacher they were ever going to have. While they learned math and science from their teachers, their system of values and beliefs was instilled at home.

I only remember having to have a little heart to heart conversation/ass chewing with one of my kids teachers and that was actually about math assignment that I thought was garbage so I told my son not to do it and then I told the teacher how stupid and asinine her assignment was and that I had instructed my son to not waste his time by doing that assignment and that if I found out she counted it against him for not doing it then heads were going to roll.
