I'm so sorry ColinsMum. I do hope that the email from the head of maths offers at least a bit of encouragement. If nothing else, it may open a line of communication with someone who will understand when you explain to him how your son devours math. It is hard for some people to understand that your child would prefer to do math in his free time, because he enjoys it that much. But I'm hoping Mr. Head of Maths will get it once you explain.
Having an effectively twice-accelerated 8yo myself, I can relate to the belief that it's not fair to not let these kiddos learn in their own natural progression. (But unfortunately I can't relate to the drive your kiddo has - mine is fairly evenly advanced right now, and 4th grade math seems appropriately challenging for my guy.)
Vent away at any time! I just wish I had some advice.
