“...they don’t teach “writing” either....or times tables.”
As for times tables, you can blame the National Council of Teachers of Mathematics. They are responsible for nearly all of the hare-brained changes in the teaching of math. Their position is rote memorization is really really bad and stifles the mathematical creativity of the students. So kids get to the 8th grade not knowing any of the times tables. On a practical level this means that doing fractions without a calculator becomes nearly impossible. Back in the day, fractions were considered 5th grade level math.
