We thought our son was stronger in verbal than math, too. However, once he was given a scribe, he showed he has great strength in math. He is still better in verbal/writing which comes easy to him, but he has shown that math is not a weakness.
You mention calculation as a weakness, which typically is a weakness for visual-spatial learners. This was the same for our son. While calculations may be a problem, math concepts are not. Your son may be able to progress through the material conceptually and should not be held up because of occassional calculation errors.
As far as the school district not knowing "how" to scribe math, it is simple. You need someone to work one-on-one writing down the answer as your son says it. Once the scribe works with your son a few times, they will learn shortcuts and it will go much faster. The scribe can always slow down and make your son state things explicitly to verify comprehension.
What math are they currently working on? Long mult./division, problem solving? I'm curious to know what "surveying" strategies are, could you elaborate?
The disabled students services are only available if you can document your disability with a physicians note and/or occupational therapist evaluation. In the case of our son, his dysgraphia causes him pain, so he cannot write more than a few words at a time, and, of course, it is messy. Most cases of dysgraphia are as you described, where you can write, but it is very messy. As long as it is documented, then you can get support services if you request them.
It sounds like the school district is trying to help, which is great. The nice thing about disabled students services at communitiy college is that they bend over backwards to help and act as your advocate to your professors. They are also very motivating and nice. Remember that community college offers math classes starting at pre-algebra. Once your son is at that level, I recommend you enroll him in your local community college for math only and see how it goes.
