I have seen some adverts for Jamie's Super school where he has has got some 'celeb pals' to come in and teach their subject, for example David Starkey is teaching History and alistair Campbell is teaching Politics. I haven't seen who is teaching Maths. I might try looking at the website , or I might keep myself in the dark until then. But opening it out, if you were going to set up your own school with a celeb Maths teacher who would you pick? My choice would be Johnny Ball. Very enthusiastic and always interesting.
