I’m so glad you are going to do something about this.
It’s the ‘lock in effect’ that being in a low maths set which is the really worrying thing in terms of your dd’s future.
Doing different work and getting used to being under stretched whilst the gap grows ever wider and the difficulty in her swapping work streams becomes more and more challenging.
I’d go into school using the most collaborative language you can, and making it clear that you aren’t going to blame them and they don’t have to get into their ‘self-justification retrenchment’ defensiveness’ mode which means they’ll block you with anything (so bloody frustrating when that happens!)... but also not letting yourself get fobbed off and not accepting such an odd turn of events as ‘truth positive’, because, sadly, this kind of thing often becomes a self fulfilling prophesy.
Whatever you do I’m sure you’ll be better than my parents :)
Your post has given me flashbacks to my childhood, where both my older sister and then me were setted low for maths in spite of being very good at primary school.
My sister was very shy and anxious so I guess I forgive them for making a mistake with her and then her getting to stressed and performing down to meet expectations, but with me it was just lazy stereotyping.
I actually scoring 100% in my maths 11+ paper, getting more than everyone in my school in spite of many of them having a lot of private tuition for their 11+ as they were going off to private schools. Yet one term later I was told I had no real ability for maths and should be happy I wasn’t in the top sets because I’d get soooo confused and lost, just like my sister (patronising idiots!).
My ineffectual parents just did a lot of hand wringing and an awful lot of werritting away about it every night into the wee small hours at home... and did precisely nothing about in beyond ridiculous anxiety within the walls of our home.
So my older sister got to her gcse year and it cane as a terrible shock to my parents to find out she was t going to be entered for the papers that would allow her to even get a ‘C’! So most uni courses wouldn’t except her. So lots of drama and tears and panic, all of which could have been avoided if my parents had been a bit wiser years before that.
At least for me I was a bit more of a fighter and didn’t let them stereotype me so much, but it was still really hard and a lot of doors were closed to me because of my lack of maths skills. I was actually very good at sciences, struggled through A-level physics and chemistry without the maths to back it up, and went on to use complex stats at university, and later in my career, but I’d definitely say that was in spite of schools maths teaching rather than because of it.
