I think you have to wait until she wants it as bad as she wanted to tie her shoes! When your DD wants to do something, she has what it takes inside her to figure it out.
I agree with your last post.
This is how I look at education:
There are the 3 Rs. Kids have to learn this stuff to function. These subjects are skills that build on each other. It doesn't take 12 years of all day instruction. In fact, it takes very little instruction. I used to tutor literacy and our tutees went from illiterate to functionally literate (approx 4th grade) in about a year and half, meeting twice a week for 1 1/2 hours with a tutor. I have no doubt that a child could skip reading instruction all together until 3rd grade and be "at grade level" in 1 year. When someone is motivated and ready, this stuff doesn't take long to learn so there isn't any reason for us to feel rushed or pressured.
Math is the same way. Grade school is very repetitive. One kid in our homeschool group didn't do any formal math studies the years he would have been in 4th and 5th grade. When he was 6th grade age, he decided he wanted to study algebra. He completed 4th, 5th and 6th grade math in less than 2 months, and started on a pre-algebra book (which really slowed him down). He mom was shocked at how easy it was for him to catch up and how little new material was presented in 4th-6th grade math.
Younger kids (like ours) are building important skills through play, cooking, art, games etc that will make these core subjects easier for them when the time comes. The better a child's language skills are when they begin reading instruction, the more quickly and easily they will progess.
Science, history and geography aren't skills -- they are knowledge. They don't build on each other the same way the 3Rs do. (in math, you need to understand basic addition before double digit addition will make much sense, but you don't need to know the parts of a plant to learn a little about the solar system). We use exciting books and fun experiences. We flow with what jumps out at the library.
Great literature is so wonderful that I think most kids who can read well, have had a love for books and stories instilled in them by being read to, and have plenty of free time will eventually enjoy them. I plan to always read aloud to my kids, even after they can read themselves. They already enjoy classics like the Wizard of Oz and Charlotte's Web, and some day I will introduce them to the authors you listed. But instead of doing an assignment in a text, we will curl up on the couch with a good book. I think that litature anthologies produced to introduce students to great writers frequently work like vaccines -- the student gets a small dose and it makes them immune from ever getting the real thing.
As far as lessons, we do them. My DDs like them. We general have lessons either right after breakfast or right after lunch. They generally last about an hour. Somedays, do don't do lessons at all. We usually start by be reading out loud (somthing short -- 15 minutes or so) and then doing something active (finger plays, ballet steps ect) and then sit at the table do some work (work books, hands on math, etc 15-20 minutes) then we do something like art, music or science (very messy or noisy and open ended). My kids are neither praised for doing lessons nor punished for not doing lessons. I think that keeping my emotions out of their learning frees them to develop their own motivation. I have it planned, but they have veto power. I don't ask them if they want to do something, I just get started and they generally join right in. Keeping it short and varying the plan helps. Constantly adjusting for what they enjoy is imperative. I think of it as the "trial and error" method of homeschooling. My 5 year old loves workbooks, so I have sought out the best ones made for someone her age/ability level. She hates flashcards so we never use them. Our lessons are truly quality time together where we do things that they enjoy. I think that how ever any of us label our homeschooling, it should be delight driven.
I think that ANY prepackage curriculum would be a diaster for us. We have tossed the whole concept of grade levels out the window (but that is another post).
Different things work for different families and I only share what work for my family so that you can take any of it that helps you.
Back to your other questions -- I don't think there is a magic age when we should suddenly begin power struggles with our kids over their learning. But I do think that the younger the child, the more damage that can be done because their entire attitiude about learning is being shaped.
sorry so long!
