My ds, 6, has become totally addicted to Carol Vorderman's Maths factor. It is really fab. However, for reasons I won't go into, dh disapproves of any product endorsed by CV and I need to find an alternative asap! I looked at Mathletics but it seems to need a school subscription, rather than an individual one. I know mumsnetters will provide the answer to this annoying dilemma!
