That's a great question Tibet! I can answer based on how I see it, but others may disagree. This will be biased by how I was taught mathematics so ther my be biases based on my school, me area, and my country.

There are two progressions through mathematics, one by grade level (2nd-3rd-4th-etc....) and the second by subject (Arithmetic-Algebra-Geometry-Trig-Calc).

These two paths intersect often, and so there are effective two full on paths through the curriculum. KA has the subject paths labeled with those categories, but it also has a grade level progression labeled. This grade level progression is infleunced and motivated by "Common Core" standard and so it has some peculiar topics occasionally.

Generally speaking, either path should provide structure in promoting the next "level" that one can achieve, based one's performance on earlier topics.

I hope this makes sense. I am sure it is confusing, especially for someone that is not from the U.S (or possibly Canada). Many of the nth grade (U.S.) standards are very US-centric, of course!

Please feel free to ask me to clarify, unless I have confused you further.
