Right now everyone is exhausted with the constant change to our lives - working from home, restricted shopping, not being able to see family and friends or go out as freely as we would like. This means we are running on very low reserves and might be unable to 'fill our cup' in order to function anywhere near our usual.
Our children are no different. Their world has changed beyond recognition. School is different if they do go in, they are limited as to who they can see and where they can go. They feel that they have no control over anything but one place they can vocalise this in in the expectation that they do some learning at home.
IME our outlook very much affects how our children react and deal with things so I would take that time to refill your cup before working out how you can help your DD with her home learning. If that means you take the DC for a walk every single day right now, fine. If it means you spend time colouring, fine. It's ok to say 'this doesn't work for us right now'.
But it seems you do want DD to do some of her learning even if she cannot do all of it.
Things which help us are to have a dedicated space to do school work - we use the dining table and a dedicated time to do it - we do 9-12 every day when I am not at work with a break half way. I appreciate this might not be easy when you are working from home but it also doesn't have to be in normal school or work hours.
I write the days tasks on a whiteboard so they can see how much they have to do. I can also use the whiteboard to show them how to work out, say a maths question or how to spell a word, getting them to give me the information as we go.
If you want her to work while you do, then find the easiest activity that she can do independently, and praise once it is done - help her feel like she can do the work by herself. It will help give her the confidence to tackle some which she might find more challenging.
But most of all, remember that if your children are happy, healthy and safe, you are doing ok. Learning at home is an ideal which we all want to ensure our children don't fall behind, but schools know this and will expect there to be a large number of learning gaps. If you can just keep her reading and writing, I'd say you are doing ok.
