Trust me, I know. I'm in the military; we get kids about 2 steps down
from the level you guys are getting. Ours largely range from "I sort of
remember long division" to "I took algebra 5 times." But it's not a
matter of them being incapable of learning it - it's just that nobody
expects them to, and they mostly don't see why they should.

I've got several friends struggling their way through remedial
community college math. One of the best ways I've found to help them
understand pre-algebra, algebra and geometry is to relate them to
tangible, real-world physics problems. Just as you relate fractions to
pie slices, you relate parabolas to projectile trajectories. Not only
does it help with their math, but when they get to physics they're
already used to it.

Now, if you combined physics 1 with algebra and physics 2 with
calculus, and expected (at a minimum) all ninth-graders to take the
first one, you might fix a lot of the problems in both physics and math
education. You might also get your kids in a mindset where they can
relate the two subjects and ask intelligent questions about both.
