I'm not a maths specialist but I'm tutoring a friend's son (she can't afford a tutor before anyone says get a propper tutor). He took GCSE a year early then no maths for a year and has started A Level. I've been going through C1 papers with him and he seems to have completely forgoten what to do although he can tell you what to do. eg rearanging a formula to make r the subject y=xrz So I aks him what he is going to do and he says, "what you do to one side of the equation you have to do to the otherside" - OK so far s good so his next move is to write down y-r=xz So we had a discussion about r being multiplied by xz so -r woun't take it away he seems to understand and then does the same sort of thing again. Multiplication and division are also giving trouble - he couldn't do long multiplication,he can sort of do the grid method exccept that when he adds at the end he might add the 10 column to the hundred. So have taught 'old fashioned' long multiplication and division. Bizarely he can do polynomial long dividion but ask him to divide 125 by 33 and he was lost. So basically any hints and tips? Has anyone come accross this before? Obviously the gap with no maths hasn't helped, but things he knows he is not applying. At the moment we are going through C1 papers with him writing down what he needs to do before attempting the questions so eg if the question gives you two points on a straight line then he has to write down the formula he will be using. Well that was the theory, he wrote down x - x1 / x2 - x3 So we are writing all the formulae in a a formulae book. I've known this child since he was 11, he is intelligent but I know he is quite lazy (typical teenager) but is that masking something like dyslexia? He also told me he got confused because the same equation in maths gives a different answer in physics!!! His teacher has finished all the C1 material, he takes the exam in January. His class are now doing S1 which he is enjoying and getting good marks for. I've told him I can't help with stats, I never did them. Basically any ideas?
