I was in a school a couple of weeks ago and saw a fantastic (IMHO) initiative between the maths and science departments where they are joining up maths and science classes (pairs of Year 7 groups which happened to be timetabled sequentially - 46 students, 2 hour class, 2 teachers - one from maths and one from science) and jointly teaching the maths topics that will be used in science in the first couple of years. They were doing probability when I visited and had just done graphs. The students really seemed to be getting a lot out of it and enjoying it. I was wondering if anyone knows whether there exists a list of the various maths skills that are needed in KS3/4 sciences (or indeed other subjects that may have a mathematical skill requirement such as geography etc.)? I have used the mighty google but not found anything yet.
