We are facing this problem consistently

Whenever we asked DD to do math, her first response is "no I will not do it" . After some push she finally does it. She usually gets 1/3 of questions wrong. Then we ask her review she does most of them correct.

We tried several options, instead of daily, which we thought may be too much, we reduced the frequency to once in. 3 days and even once in a week. Her response is same each time and again makes 1/3 of answers wrong and on review without any explanation or coaching by us she does most of them correct again

Most of her mistakes are simple and silly. She does mistakes in simple additions or when she writes the numbers on a paper to solve them, she makes mistakes I.e write one or two numbers different like instead of 1860 she may write 1870 etc

She is fourth grader and currently working on 6th grade math. We are thinking 6 th grade may be too much. But looking at mistakes she does as described above or doing them right without any additional coaching or explanation making us really frustrated

Any suggestion?

Highly appreciated
