This child, according to OP, KNOWS the value of education. SO now it's up to Dad to teach her what that involves. That she is responsible for getting her work done. A lot to expect of a 5/6yo? Yep. But... doable.
I've said it before - I have always been rather hands-off when it came to school/homework. Kindy homework? Busy work. I taught my kids in other ways - more hands on ways. But worksheets, etc? Please, Math can be learned via cooking, science via being out of doors and other fun activities, reading... by reading books together. And so on and so forth.
As for tracking vs not? Hoenstly? I think not tracking helps those who are less able and hurts those who are more. Based on personal experience, the brighter kids end up helping teach the less so. At the cost of their own time/work. When my kid was bringing home hours of homework - because he spent his school time helping other kids instead of doing is own classwork (at the behest of the teacher)? Not acceptable.
Tracking benefits the brighter kids as they get that attention they need. Does it surprise anyone that our representation in science/math/technology has gone down wrt other countries? Why our graduate schools are full of foreigners? OUR best and brightest are being thrown onto the pyre of inclusion. And they suffer for it.
Oh, and CO? Is "average" in Math & Science. Lower than states that track. But... I guess that's "good enough" for some...
