I would echo what everyone else has said. She will have her own strengths, and should be praised for those. It’s no good being clever if no one ever invites you to their party because you are unkind!
However, on a practical level, there are things you can do.
Read to her. Encourage a love of stories. If she likes books and stories she’s more likely to want to be able to read for herself and that inner motivation is a big step forward.
Little and often. If she needs to learn to count in twos, for example, do it in the car or on a walk, once or twice through, then leave it. Do it daily, with a short and sweet approach. Same with reading books.
Get her to read everyday but if she’s tired, she only needs to read a page or two, not the whole book. It gets her into the habit of doing some things daily, which means she is less likely to fight you over it because she knows it happens every day, but isn’t too onerous.
I do understand. I’m a TA but also have a daughter in Y2 who has learning difficulties. She has just mastered some of the year 1 ‘tricky’ words (words you can’t sound out, you just have to recognise, like ‘some’ because the spelling doesn’t work if you sound it out phonetically), after me doing them daily with her in lockdown. So 10 weeks to learn half a dozen words that she should have known a year ago. But for her, it is huge, she’s been praised by everyone (we read them to granny and auntie over Skype, so they could join in the praise) and it makes her life a little bit easier being able to read some of the words. And when the words come up in her reading books, I do a thing of saying “well done, you read it, and you didn’t know that a few weeks ago, clever girl”. She will always find it hard but little and often really helps.
