duet 119.01.895 RK3 1902, May 13. Gift of the Publishers TRANSFERRED TO COPYRIGHT, 1901, BY ISAAC O. WINSLOW. ENTERED AT STATIONERS' HALL, LONDON. WIN. AR. III. M. 3 PURPOSES AND DISTINCTIVE FEATURES THE purposes of this series of Arithmetics are: 1. To present the subjects in a spiral order. Instead of presenting the general subjects of addition, subtraction, multiplication, division, fractions, etc., as complete wholes in regular succession, each subject is divided into parts with reference to the difficulty of the principles involved. The easier principles of various subjects are treated together, while the more difficult principles are reserved until the child has gained the power to apprehend them easily. 2. To make the work easy. In the belief that it is better to keep mathematical work a little behind the child's mental grasp than to advance it beyond that limit, the work designed for the different grades has been made somewhat easier than that usually found in text-books. The pupil is kept busy with a varied application of the principles that he has already mastered instead of being too rapidly crowded forward into greater difficulties. 3. To give the subject variety and interest. The problems are based upon facts and principles gathered from the different branches of study, as history, geography, nature study, astronomy, and physics, as well as on the customary commercial transactions, thus correlating arithmetic with other studies and adding distinctly to its vividness and interest. |
