I recommend this book for beginners: Start Quilting (3rd edition) by Alex Anderson.
I find it a great clear, concise and well-illustrated book for beginners. Alex introduces the basic shapes (squares, rectangles & triangles), basic/recommended tools, provides easy to understand directions and descriptions as well as helpful tips and shortcuts. It's next to my machine; my within-reach-reference.
At least pick up a copy and flip through it.
