At school in the 70s I learned to multiply and divide numbers by multiples of 10 by 'moving the point'. Later, when training in a teacher, I was taught that on no account EVER was I to talk to children about 'moving the point', as....the decimal point doesn't move. I was to teach children, using place value charts, that it's the digits that move. 'The decimal point doesn't move' has in fact become something of a mantra repeated by children at secondary stage. The only problem is....WHY do so many of them, having been taught 'move the digits', years later, have such problems multiplying and dividing numbers by multiples of 10 where decimals are involved? My suggestion is that 'moving the digits', however mathematically correct, hasn't worked for students in general. 'Move the point' is so much easier. Not only did generations of schoolchildren appear to manage fine with 'move the point', but my internet research suggests that the whole of America still teaches 'move the point'! The bulk of my teaching over the past 15 years has been KS2 and KS3, and in recent years I've rebelled a little. KS2 I've religiously taught 'move the digits' (would get in Big Trub if did anything else!). KS3 (and a few KS4, even Higher GCSE) I will show students for whom 'move the digits' appears to have failed that 'move the point' is a great short-cut, but of course with 'you-will-remember-that-the-decimal-point-isn't-really-moving-won't-you?' to cover myself! What do others think?
