Excerpt from Elementary School Mathematics by Grades, Vol. 6: Commercial Affairs Boys and girls in the upper grammar grades of the free common schools of American towns and cities are pursuing courses Of study by no means uniform. There is perhaps no general agreement in educational practice beyond the fact that it is considered desirable that boys and' girls should advance from elementary to secondary schools at about fourteen years of age. There are, however, marked tendencies to agree upon several other points. There is increasing agreement to the effect that pupils in the upper grammar grades should study what will most benefit them in discipline and in knowledge. We have come to see in the light of the new knowledge Of the facts and principles Of mental and moral growth, presented by genetic psychology, that what a child enjoys learning he profits by, and that what he profits by develops in him the normal life Of the child, which is the guarantee of an efficient life as an adult. There is a growing tendency to decrease the range of arithmetical instruction and to introduce much more geometrical instruc tion. There is also a distinct tendency to rely more and more upon the various forms of manual training in the education Of boys and girls; and this development along the lines of the industrial arts, which afford the materials of manual mental discipline, lends itself notably to the encouragement Of the study of geometry early in life.
