From your point of view it is understandable that you want your son inculded and engaged and are willing to do everything to make this happen. But I do feel you are looking at it from only your perspective. There will be kids there that are twice your child's age. Maybe some of them have been signed up because they are not very good at math and they want this to be an uplifting experience for them? Now from another child's point of view, if there is a kid half your age and knows math better than you, how do you think that will make them feel? I think at your son's age you will be able to find so many resources for math for him, there is really very little benefit for him to be in that class.
