My daughter has just started her GCSE course which she will be doing over three years (she's in year 9). Maths is not her strong point so she has been asking me to help her to understand and work through her homework tasks.
For background, I got an A at GCSE Maths about 25 years ago, and have a 2:1 degree so whilst by no means a genius, I am fairly well-educated and work in an education field (not maths).
I have been completely baffled by a lot of her maths work, and we have had to watch how-to videos together (as recommended by school) to understand how to do some of the work. It is things like indices, including fractional indices, equations including fractions and minus numbers, surds (literally never heard that word before yesterday) etc. It is all deeply theoretical, and with no practical application that I can see in real life.
Considering that GCSE Maths is a basic requirement of pretty much any job and higher education course, this is insane surely? I can understand requiring people to have a decent working knowledge of usable day to day maths, percentages, ratios, interest rates, budgets, weights and measures etc. But why does everyone, need to know all this in-depth theoretical stuff? My husband works in a finance department and also has no idea about most of this stuff and never has to use it in his job.
