One handy idea for a child who has been struggling at school is to start by taking all the pressure off and focus on letting her recover, enjoy herself, and develop her interests. So for a child whose heart sinks at the sight of a maths workbook, don't even mention maths, not at first anyway.
What does your daughter love to do? What makes her come alive? Whatever it is, do that. Take her swimming, read her stories, buy her some new art materials. Until she is relaxed and feels good about herself, she won't be able to learn well.
Once you see that she is happier, you could start to introduce some formal learning if you want, beginning with her favourite subjects so she gets off to a good start and her confidence builds. During that process, if anything is making her unhappy, see whether there are alternative approaches which work better. Try not to spend too much at first - if she hates the first reading scheme you try, you want to be in a position to leave it behind and use a different one rather than feeling stuck with the one you paid a lot of money for.
You don't have to do formal learning at all. Some home ed families don't, especially with younger children, and find that their kids learn well through their daily life and discussions. This informal approach can be used for a few years or right the way through. My kids are now 23 and 16 and were never made to do any "lessons", but that doesn't mean they didn't learn!
