I need to convince my son that a good grade in his maths GCSE is important. He is strong in the arts, languages etc and is adamant that he won't need more than the maths he has already acquired. He is a great debater and budding politician and runs rings around me in an argument. I need someone to help me explain why a university or employer requires maths even if the candidate won't be using maths for their studies or work. He feels they are narrow-minded and just awkward. I have used all the obvious arguments; don't narrow your options, you never know, you need maths for everyday living, etc.., but I would love something a little more meaty that might suggest that maths helps support other areas of study, forms connections in the brain... I don't know. He is the type of boy who will willingly do something if he can see a good reason for doing it, but he doesn't like doing things 'just because...'.
