 HOW LESSONS SHOULD BE GIVEN 113 child's mind through such a lesson, and not the object for which the lesson was given. To obtain a simple lesson from a teacher who has been prepared according to the ordinary methods, is a very diffi­cult task. I remember that, after having explained the material fully and in detail, I called upon one of my teach­ers to teach, by means of the geometric insets, the differ­ence between a square and a triangle. The task of the teacher was simply to fit a square and a triangle of wood into the empty spaces made to receive them. She should then have shown the child how to follow with his finger the contours of the wooden pieces and of the frames into which they fit, saying, meanwhile, " This is a square — this is a triangle." The teacher whom I had called upon began by having the child touch the square, saying, " This is a line,— another,— another,— and another. There are four lines: count them with your little finger and tell me how many there are. And the corners,— count the cor­ners, feel them with your little finger. See, there are four corners too. Look at this piece well. It is a square." I corrected the teacher, telling her that in this way she was not teaching the child to recognise a form, but was giving him an idea of sides, of angles, of number, and that this was a very different thing from that which she was to teach in this lesson. " But," she said, trying to justify herself, " it is the same thing." It is not, how­ever, the same thing. It is the geometric analysis and the mathematics of the thing. It would be possible to have an idea of the form of the quadrilateral without knowing how to count to four, and, therefore, without ap­preciating the number of sides and angles. The sides and the angles are abstractions which in themselves do not ex-
