I was aware her reading isn't brilliant (I was a late reader...my mother took me took an ed psych who found a reason, and I caught up..by the time I was 9 I have a reading age of 14).
Her spelling is shocking. He has difficulty hearing all the sounds in words, but we are working on it, and I have faith she won't leave primary school illiterate.
Her writing isn't great, but I have been working on her fine motor skills since I realised they were poor 2.5 years ago, and she has improved a lot.
But I had always thought her maths was pretty much OK. It certainly was when she was in pre-school ( I work in early years) And seemed pretty much on track in reception. Her reception teacher seemed to think she would catch up in literacy and told me not to worry about her as she would get all 3's in her SATs in Y2. (This is now looking extremely unlikely)
I've recently realised her maths is way below average. 18 months ago she wasn't struggling, but she seems not only to have made no progress, but to have regressed. Simple concepts like how many 10p coins, and which other coins does she need to make 21p are a huge challenge for her.
I am totally bemused by this. Her class teacher this year has moved her up into the middle group partly because DD nagged her to, and partly because DD is as so able verbally. If you met her and had a chat with her, you certainly wouldn't think she would be in the bottom sets at school.
Any one know what's going on here? Is it because we are a talkative family, and with two older siblings she's picked up a decent vocabulary? We're not a particularly maths orientated family....which I realised when we were ordering a cooked breakfast recently with friends and someone asked DS how many different combinations of bacon/egg/beans etc it was possible to order. We never do things like that with the DC, but my older DC seemed to have muddled through and ended up near the top of the class.
Feel free to tell me DD is just thick. Which is fine, except she wasn't before. 
If you got this far thank you!
