Fig 2.––The Montessori Paedometer.

      My pedometer forms part of the equipment of a “Children’s House.” After various modifications I have now reduced this instrument to a very practical form. (Fig. 2.)

      The purpose of the pedometer, as its name shows, is to measure the children. It consists of a wide rectangular board, forming the base, from the center of which rise two wooden posts held together at the top by a narrow flat piece of metal. To each post is connected a horizontal metal rod––the indicator––which runs up and down by means of a casing, also of metal. This metal casing is made in one piece with the indicator, to the end of which is fixed an india-rubber ball. On one side, that is to say, behind one of the two tall vertical wooden posts, there is a small seat, also of wood. The two tall wooden posts are graduated. The post to which the seat is fixed is graduated from the surface of the seat to the top, whilst the other is graduated from the wooden board at the base to the top, i.e. to a height of 1.5 16 meters. On the side containing the seat the height of the child seated is measured, on the other side the child’s full stature. The practical value of this instrument lies in the possibility of measuring two children at the same time, and in the fact that the children themselves cooperate in taking the measurements. In fact, they learn to take off their shoes and to place themselves in the correct position on the pedometer. They find no difficulty in raising and lowering the metal indicators, which are held so firmly in place by means of the metal casing that they cannot deviate from their horizontal position even when used by inexpert hands. Moreover they run extremely easily, so that very little strength is required to move them. The little india-rubber balls prevent the children from hurting themselves should they inadvertently knock their heads against the metal indicator.

      The children are very fond of the pedometer. “Shall we measure ourselves?” is one of the proposals which they make most willingly and with the greatest likelihood of finding many of their companions to join them. They also take great care of the pedometer, dusting it, and polishing 17 its metal parts. All the surfaces of the pedometer are so smooth and well polished that they invite the care that is taken of them, and by their appearance when finished fully repay the trouble taken.

      The pedometer represents the scientific part of the method, because it has reference to the anthropological and psychological study made of the children, each of whom has his own biographical record. This biographical record follows the history of the child’s development according to the observations which it is possible to make by the application of my method. This subject is dealt with at length in my other books. A series of cinematograph pictures has been taken of the pedometer at a moment when the children are being measured. They are seen coming of their own accord, even the very smallest, to take their places at the instrument.

THE METHOD

      The technique of my method as it follows the guidance of the natural physiological and psychical development of the child, may be divided into three parts: 18

      The care and management of the environment itself afford the principal means of motor education, while sensory education and the education of language are provided for by my didactic material.

       The didactic material for the education of the senses consists of:
