Just curious about when this is taught to average kids in your area. Which grade? If you want to list when it is introduced and when it should be mastered, that would make more sense to you.

Definitely mastered by 4th grade in my school. Although it's double digit addition, it doesn't require regrouping. I'll guess that it's introduced around 1st grade.
Early elementary school, but if a child doesn't know it in 3rd, 4th, 5th grade, then he can learn it quickly and easily (barring no learning problems). I read somewhere that all of the basics of math can be taught and mastered in under 20 hours, if the child is developmentally/intellectually ready to learn.

It may be possible but it is not happening. I am subbing today for a 5th grade math teacher and many of the students are struggling with adding, subrtracting and dividing fractions, and basic multipication and division. As I walk around the class, I see kids counting on their fingers. This is not uncommon. In many of the classes where I sub, many students are can only do basic math problems if they use a calculator.
This is the problem that my first two 5th grade classes had problems with today:
