Well, I don't consider it algebra when my 1st grader answers x + 1 = 10, although it's intended to lay the groundwork, just as you say. I'd consider solving 108 = 1/2h(27) to be different, though you could do it by trial and error. However, my DD did it the traditional way. It doesn't really matter. I was just curious because I didn't expect this in her current course and wondered if it was a Common Core change.
