Mathematics is indeed not taught in a proof-based manner, but I would also argue that it takes a lot of training to teach proof-based maths to primary grade students. It is far harder than teaching maths to undergrads or high schoolers. Which is the real reason it doesn't happen in schools. > I didn't enjoy the endless calculations of long division in grade school... Sure, everyone has their own cup of coffee. But drummers, for instance, practice the same beats over and over again for dozens of hours to perfect them. Not very different from doing long division over and over again.
