Why every lesson needs a good lead-in

You’ve probably had one of those teachers who begins each lesson by announcing, “Ok, class, today we’re going to learn about (insert topic here).” Or who waltzes in, and, without any preamble, says, “Open your books to page 16 and let’s get started.” Unless you’re really, really into the material in that book, you’re probably not feeling terribly excited about the class. And even if you are really into the material, “open your book” is something you could just as easily do at home from your couch, right?
