The local ITV Granada news is reporting that school children in Rochdale are getting lessons in brushing their teeth from their teachers (although this does appear to be relative old news). So now 3 minutes a day is dedicated to a basic matter of hygiene. This could be the source of some debate as to the wisdom of this addition of the curriculum.
More surprising was the explanation of the justification for doing this. National statistics suggest that the percentage of children under 5 with tooth decay stands at 1.1% across the UK. In contrast, among Rochdale’s under 5s 2.1% have tooth decay. So there seems to be some quantitative basis for the decision.
However, ITV Granada seems to be of the understanding that this means that Rochdale’s tooth decay rate among under 5s is 50% higher than the national average. How can this be? A rough approximation would suggest that they could make a much more sensational claim.
Perhaps the schools could introduce a bits of maths into curriculum?
„Cif PowerPro Naturals Kitchen & Multipurpose is 95% naturally derived Water and plant based cleaning agents“
– Which is the basis of the new advertising campaign. This list of potential natural ingredients shows promise but my maths would suggest that there’s 5% in there that are your basic nasty chemicals. Equally if we are thinking about the maths of this why package up the water? And what exactly is a naturally derived water cleaning agent? Isn’t that just water?
