This is a skill I owe it to humanity to share, but not right now. Here's something I prepared earlier.
It was written for the Children's Book Council of Australia, NSW Branch journal, formerly News and Views, now iRead. You can find that version here, after about the middle of June, but this is a revised version.
We begin with the hypothesis that any subject can be taught effectively in some intellectually honest form to any child at any stage of development.
So: four things are required:
* careful, considered, logically structured writing;
* interesting content (or useful content or both); and most of all,
* a guided journey into curiosity and wonder.
Now you really want to know what that list was? Those names were the rivers encountered by Ludwig Leichhardt in 1844-45, as he explored northwards, in order. It is totally useless for anything at all, other than as a frightening example of what comes from completely futile "education".
You will see signs of that in a book to be published on October 1 by the National Library of Australia. It is to be called The Big Book of Australian History, and it will be available in both print as an epub-formatted e-book with loads and loads of links to original sources.
