At the end of the fifth year, as the natural outcome of its instinctive effort to experiment and learn, acting amidst wisely ordered surroundings, the little child should have acquired a certain definite foundation for the educational structure. It should have a vast variety of perceptions stored in its mind, and a vocabulary of three or four thousand words, and among these, and holding them together, there should be certain structural and cardinal ideas. They are ideas that will have been gradually and imperceptibly instilled, and they are necessary as the basis of a sound mental existence. There must be, to begin with, a developing sense and feeling for truth and for duty as something distinct and occasionally conflicting with immediate impulse and desire, and there must be certain clear intellectual elements established already almost impregnably in the mind, certain primary distinctions and classifications. Many children are called stupid, and begin their educational career with needless difficulty through an unsoundness of these fundamental intellectual elements, an unsoundness in no way inherent, but the result of accident and neglect. And a starting handicap of this sort may go on increasing right through the whole life. The child at five, unless it is colour blind, should know the range of colours by name, and distinguish them easily, blue and green not excepted; it should be able to distinguish pink from pale red and crimson from scarlet. [Footnote: There could be a set of colour bands in the book that the English Language Society might publish.] Many children through the neglect of those about them do not distinguish these colours until a very much later age. I think also--in spite of the fact that many adults go vague and ignorant on these points--that a child of five may have been taught to distinguish between a square, a circle, an oval, a triangle and an oblong, and to use these words. It is easier to keep hold of ideas with words than without them, and none of these words should be impossible by five. The child should also know familiarly by means of toys, wood blocks and so on, many elementary solid forms. It is matter of regret that in common language we have no easy, convenient words for many of these forms, and instead of being learnt easily and naturally in play, they are left undistinguished, and have to be studied later under circumstances of forbidding technicality. It would be quite easy to teach the child in an incidental way to distinguish cube, cylinder, cone, sphere (or ball), prolate spheroid (which might be called “egg”), oblate spheroid (which might be called “squatty ball”), the pyramid, and various parallelepipeds, as, for example, the square slab, the oblong slab, the brick, and post. He could have these things added to his box of bricks by degrees, he would build with them and combine them and play with them over and over again, and absorb an intimate knowledge of their properties, just at the age when such
