Today we are doing frame-by-frame animation. Much like a flip-book, frame-by-frame animation entails drawing one frome, adding a new page [we call it a keyframe] and then drawing a new picture. When flipping through the images one-by-one, the images appear to move. This is the same method used to create the Disney cartoons. Todays animators use computers in a process similar to what we're doing here.
