All sorts of interesting points.
Do mathematicians get less respect than scientists? Depends who you are asking? But also depends on who is speaking. Part of the problem with mathematicians is that often what they are discussing is impenetrable - the math they work with day to day is far and away beyond 'mainstream' ability in student/ adult population.
But government funding in Higher Education is related to STEM - and very definitely includes mathematics. This is a bit beyond primary level - but there is a uk website about careers using mathematics (starts addressing 11 year olds and up: www.mathscareers.org.uk/.
Now in terms of being a Mum on Mumsnet and caring - trust me (and I think many hear will agree) I regularly try my best to explain the curriculum, give feedback and help at various common hurdles. Multiplication is a popular topic (at the moment) but we've had long discussions about how to help with carrying over numbers in addition/ subtraction, problems with adding/ subtracting big numbers and 'the column method'. People have also asked about telling times and game suggestions. There also was a great 'tricky problem' posted a while back - which involved closing doors in a certain way 1000 times and then working out which doors were open and why. Took me a while to work out with DD - but we really enjoyed ourselves.
Mumsnet also put me on to Woodland Junior School mathszone: resources.woodlands-junior.kent.sch.uk/maths/, as well as many other fab resources. It was also a joy to be pointed in the direct of NRICH Math from Mumsnet: nrich.maths.org/frontpage - fabulous programme and all sorts of brain teasing/ maths exploration work to play with.
Communication from schools could be better. Our schools official curriculum - as published on their website - for maths is TERM 1 - A1 - C1, Term 2 - A2 - C2 and Term 3 - A3 - C3. Trying to ask them about more work/ practice ideas/ workbook recommendations led to a stream of abuse (I presumed I must have asked in a rude way, but DH was so offended by the abuse he received when he attempted similar to try and help our DD1 - he was so offended that he refused to deal with 'that woman' for the rest of the school year.)
Now the point many raise here and which I do totally agree with is that without core maths skills (calculation skills, initial geometry understanding [things like shapes (2D/3D)/ area/ perimeter and regular problem solving work] - children will really struggle to fully engage with science and maths curriculum in senior school.
Is maths important? - yes. Should parents get more directly involved? Yes. But I suspect - poor communication from school, personal uncertainty/ insecurity of maths skills/ appropriate techniques on the part of parents and frankly unapproachable teaching professionals all corroborate to put maths on the back burner, which is a crying shame!
