Starting about a decade back (of which I am aware), our district included "elementary" algebra and "elementary" geometry in the elementary math curriculum. I used to refer to it as "kiddie" algebra because it was very basic algebraic concepts in an elementary friendly approach. Compared to 30 years ago, more than half of the current elementary math curriculum are new. In addition to "algebra" and "geometry", there are units on probability and statistics (the three measures of central tendency), graphing and measurements that go far beyond what used to be covered in elementary math.

The "algebra" and "geometry" in pre-algebra naturally extend beyond the basics covered in elementary math. Regarding the trigonometry, I am not sure that it is covered in the other pre-algebra textbooks as that certainly was not covered when I studied pre-algebra.
