I think there’s also value in figuring things out with your kid. When I was helping my D through chemistry, I would sit next to her and read the textbook to figure how to do the homework. Sure it was painful, but in the process my D saw that the textbook actually did explain things if you put some work into it. Once I read the text and figured things out, I’d go over it again with her and basically say, “see, this part of the text is applying that that step in the homework, and here’s what it’s saying to do.”
Once my W asked D, “did Daddy know how to do the homework?” And D replied, “Not right away but somehow he’s always able to figure it out.” That ability to “figure it out” is what I tried to teach my D, moreso than how to solve a particular bit of homework.
I think that’s a different aspect of the same principle sylvan8798 is saying above.
