All day long the child is ceaselessly active. The value of this activity can hardly be overestimated. It not only leads to healthy growth, but is a means through which the child learns himself and the world. Everything that the child sees excites him to react to it or upon it. He gets possession of it. He bites it. He pounds it. He throws it. In this way he learns the properties of things and the characteristics of forces. Through play and imitation, in a very few years the child comes to a successful adjustment in his world. Play and imitation are the great avenues of activity in early life. Even in later life, we seldom accomplish anything great or worth while until the thing becomes play to us, until we throw our whole being into it as we do in play, until it is an expression of ourselves as play is in our childhood. The proper use of play gives us the solution of many of the problems of early education. Play has two functions in the school: (1) Motor play is necessary to growth, development, and health. The constant activity of the child is what brings about healthy growth. In the country it is not difficult for children to get plenty of the proper kind of exercise, but in the larger cities it is difficult. Nevertheless, opportunity for play should be provided for every child, no matter what the trouble or expense, for without play children cannot become normal human beings. Everywhere parents and teachers should plan for the play life of the children. (2) In the primary grades play can have a large place in the actual work of the school. The early work of education is to a large extent getting the tools of knowledge and thought and work--reading, spelling, writing, correct speech, correct writing, the elementary processes of arithmetic, etc. In many ways play can be used in acquiring these tools. One aspect of play particularly should have a large place in education; namely, the manipulative tendencies of children. This is essentially play. Children wish to handle and manipulate everything that attracts their attention. They wish to tear it to pieces and to put it together. This is nature's way of teaching, and by it children learn the properties and structures of things. They thereby learn what things do and what can be done with them. Teachers and parents should foster these manipulative tendencies and use them for the child's good. These tendencies are an aspect of curiosity. We want to know. We are unhappy as long as a thing is before us which we do not understand, which has some mystery about it. Nature has developed these tendencies in us, for without a knowledge of our surroundings we could not live. The child therefore has in his nature the basis of his education. We have but to know this nature and wisely use and manipulate it to achieve the child's education.
