Excerpt from Arithmetic by Grades for Inductive Teaching, Drilling and Testing, Vol. 6: Mensuration, Denominate Numbers, Metric System Percentage and Simple Applications, Business Transactions and Accounts In addition to the above features, some of which are distinctively new so far as American text-books are concerned, there is the separation of pupils' exercises for practice into small books some what ou the lines of gradation in City graded schools. By this ar rangement there are gained greater convenience of handling and economy of wear than in the use of a large book which is intended to be used for several years by the same pupil. The problems of Section I of this book are given as a review of previous work. Little time need be given in drill upon them, if the work of previous books has been thoroughly done. The continued use of objects in teaching Mensuration and Denominate Numbers is strongly advised as well as the pupils' practice of drawing in the illustration of problems, especially when such drawing will tend to make clear an unfamiliar or difficult process. Since the Metric System of Measures and Weights is not in common use, it is not necessary to give very extended or long continued practice in it. Yet enough of practice should be given to show the pupils the great advantage of simplicity and economy of time that it has over our complex system.
