If you want to know how to home school a child, you need to start by finding out how your child thinks and learns. There are some books and specialists that can help you identify the child's learning patterns, and thus will help you adjust your teaching techniques - as, after all, adaptability and flexibility are the strongest points of home schooling.
You will also need to select the curriculum and method for home schooling.
There are no success recipes - or rather, each home schooling family has its own individual success story, but there are some guidelines that could help you.
The traditional approach is the textbook approach, focused on reading, writing, grammar and spelling, with many practice hours and exercises needed to develop the skills.
There is also the so-called "classical" approach, which starts from the basic facts of life and the skills necessary for getting around, and progresses towards logic and advanced language skills. This method will focus on the works and texts of the literary Western world.
Another method, called unit studies, relates several disciplines to a particular theme (a religious theme, for instance).
Finally, there is the "delight-directed" approach, which encourages the child to follow his or hers own interests, by providing all the necessary means and tools. The essential concept is that education is its own reward, and the child should really be passionate about something.
Since you know your own child better than anybody else could, it's up to you to decide which method is the best. However, don't be afraid to ask for help if you feel things are not progressing quite as you would have liked them to.
