1. Acquire a book. It doesn't matter what type; if it has pages, you can turn them! Not just books have pages: magazines, leaflets, calenders, they all have pages to turn. Once you have a book, you're ready to begin.
2. Examine the layout of the pages. With most books, the pages turn over to the left side. However, some books and indeed calenders have pages the turn upwards and some foreign texts write right to left, so the pages may turn to the right, opposite to those of the western world. Making sure you have the book the right way up is also a good idea.
3. Open the book. To do this, put your hands on either side of the book, place your thumbs roughly in the middle of the side that's facing towards you and separate them, gripping the book as you go; this will cause the book to part and the book to be now open. Normally you would want to start from the beginning of the book, where the story often begins, but to learn how to turn a page, you can start anywhere in the book.
4. Place the book on its spine, either in your hand, on a flat surface or other area so that the cover is facing downwards and the open pages upwards. This makes it much easier to turn pages because of gravity and hold your position in the book.
