Poor you. It is relentless. I suggest you plan out the day so use a visual timetable for her. I found it hard at that age as my eldest woke so bloody early that by 9.30 I felt I had done full day. The expense can get a lot too.
So, suggest you create a school like timetable for her ( and you).
In a day do one going out (walk slowly) to somewhere, library, we used to go to a hen farm, national trust garden, park, playground, museum. Some places have activity things for kids over the school holiday - look them up as they are often free.
I hate craft with a vengence. No paint. Do one making activity, with lego, playdoh, magnetics.
Do a school activity so you can get her to make letters out of playdoh to spell words. She will be on cvc or ccvc words. Get her a whiteboard with washable pens, she can write words. Keep a diary. Short sentences only. Maths - get her to count apples, take away, add - pasta good for this. Get her to teach something to her toys like a teacher - that should buy you ten mins.
Reading, twenty mins a day snuggled with reading to her.
Watching tv - honestly, just do it for your own sanity.
Imaginative stuff
Indoor tents (two chairs and a sheet, duvet cover over the top)
Going to theseaside ( pretend jumping over the waves, etc)
Schools
Helping activities
Teach her to make scrambled eggs. They can sit on the side and stir stuff.
Cakes
For tidy up time, there is a song that our reception teacher plays and they tidy up to that.
It is honestly relentless. I totally get the money thing. Is it worth, rather than paying to go out to places, that you put her one day or half day a week into a sports club or holiday club for your sanity.
It does get better, honest.
