Excerpt from Arithmetic by Grades, Vol. 1 This book, the first in a new series of practical arithmetics, is designed to impart to the pupils a mastery of the fundamental processes in manipulating integers, familiarity with a few rudi mentary fractions, and a facility in simple calculation. It is hoped that the method, and particularly the manner, of presenta tion will not only guide but also interest the pupils in the ordinary applications of whole numbers and simple fractions to everyday problems. The authors have never lost sight of the fact that a thorough grounding in the fundamental operations is the key to future success in arithmetical computation, and that proficiency in the use of tables and factors must be gained through drill. Accord ingly the work in problems in the earlier books of the series has been subordinated to drill practice. It is hoped that sufficient and varied drill work has been provided so that abstract calcula tion may become almost automatic, and the pupil may acquire that accuracy and rapidity which are necessary if the thought work of the later years is to be unhampered. The fact, however, that all work in the abstract should follow as a result of a con crete and urgent need in the pupil's mind, that there must be a vital point of contact between the pupil and the new topic or process, has been kept in view and, as a rule, all drill work and new processes are approached in problem form.
