it is not as simple as you think! Not at all. Unschooling is, in my view, the hardest part of teaching.
When unschooling, you go the opposite direction than secular schooling. When unschooling you choose to let kids learn in their own time, with their own wish and will. Of course creating opportunities for kids to learn is fundamental.
Creating the place where kids can learn, filled with resources such as books, art&craft ready to be use, maybe a blackboard and some chairs and a table.
Kids are aware of the environment they are in and if not push to learn, they will start their own activities and learn at their own pace. Mash'Allah.
Some time ago I bought a book called 'The Unschooling handbook' by Mary Griffith.
A well written book, full of real unschooling stories.
I enjoyed the reading and learnt so much more about unschooling.
