I call bullshit on this. 18 months of maths is a completely vacuous measure of anything and this is pandering to teachers getting even more lazy and dependent on technology as a magic bullet.
As a parent in the UK with three children at school, I can safely say that the problem is that mathematics teaching is just totally shit. The methods are totally ineffective and the fundamentals just aren't taught. It's about teaching the mechanics of passing tests, particularly at primary level which is about the SATs and nothing else. That's why this seems like such a wonderful headline and the BBC sensationalises it.
Teachers buy in every technical measure and scheme that avoids introspection and looking at the real problem.
