As an LSA who spends a lot of my time in bottom set Maths groups there is a strong case for more use of Functional Skills as an option. I see Year 10/11 pupils who struggle with basic numeracy, can't cope with fractions and percentages, find powers and indices confusing, have forgotten how the metric units system works - and, what is worse, don't seem to care, don't seem to realise that they will be easy prey for dodgy loans with extortionate interest rates, will be unable to see if they've been overcharged in the pub and will misunderstand every statistic in the news (or possibly, be responsible for producing dodgy press releases themselves).
I love Maths - I love the beauty, and abstraction, and the complexity, and the patterns. But many of the pupils I help are simply learning tricks to answer particular types of questions, tricks which they can never quite apply to a slightly different version. Even something as basic as reading a "word problem" and knowing which numbers should be added or subtracted to get "the answer" seems to elude them....
At the very least, maybe all MPs should be made to pass an exam in basic numeracy....
