Training the mind's eye
"Making sure maths solves real problems" (Professional, 24 January) misses one important point: mental maths needs to be carried out through mental images. But children struggling with maths don't have mental images of numbers; only about half of people develop this ability naturally. Teaching the skill to all primary school students would save a fortune in extra maths coaching and lead to much higher standards of numeracy.
