As a former maths teacher I think this is an appalling idea. It's the worst kind of populist dog-whistling. It's based on the premise that there's a problem with basic numeracy, which outside of lurid tabloid stories doesn't really exist. And it isn't about improving education, it's about political point-scoring.
Anyway, what maths are you going to teach to those who have decided that it's not a subject for them? Hours of basic algebra drills? These are 16-18 year-olds, you can legislate to force schools to have the classes but you can't make young people of that age turn up to the classes.
This is one of the very few things I agreed with Margaret Thatcher (in a minority in her own Cabinet) about – what's taught in schools is a matter for teachers, not politicians.
