Exactly. I struggled with retaining maths. In the lesson things are easy, but give it a few days and I forget how it’s done. I’m the sort of person who needs maths to be repeated ad nauseam before it sticks, and at school topics move on so quick
I honestly wonder how wide spread this is.
My kids had overlearning thanks to maths factor - needed same with spelling and reading - phonics being a huge help for them.
They also need things explicitly being pointed out - so they had half = divide by 2 = times by a half - pointed out as the background noise to their lives as mathametical literacy it's just there in our house - from kids TV - number jack, number blocks - to parental coversations to maths games - to general life spliting cake, toys up.
I remember the frusation with the extra spelling lessons I was made to do during GCSE English with a teacher who'd never struggled with spelling. I remember asking for rules/guidance about adding suffixes and changing works - she said oh never thought about it you'll just have to learn each case. Luckily for our kids there were explained in a spelling program we did with practise and exceptions learnt.
The other advice I was constantly given was sound out words. Problem there is I really struggle to hear sounds in words - affected my early speach - and then I hadn't been taught phonics - and thus I either hadn't known all the trigraphs or diagphs or I was really shaky on them even if I could hear the sound didn't always know which letters it could be. No-one grasphed why I struggled they'd shrug saying well English is hard to spell phonically - so why suggest it as a statergy.
It was an exercise in frustration so stopped going and went back to the actual English lessons I'd been missing. I spent maths exams plugging maths gaps with number knowledge I did have - thats to solid maths teaching - and rest using synonyms I could spell or reconstructing sentences on fly to get round words I coudl not. I can see why some explain dsyleixa as a drag - you end up doing so much to appear the same and then get told your stupid or lazy or should just get things others do.
Good teaching is clearly incredibly helpful - having the basics solid is huge help - but not sure that schools can cover all the practise that's needed by some.
DC early maths teaching in schools all revolved around fun games - and they frequently missed, forgot or never understood the underlying principlas behind the games. So do wonder if some schools make learning maths harder for some kids with the techniques they use.
