Book Description
Excerpt from Applied Arithmetic, Vol. 3: The Three Essentials This book is the second of a three-book series and is intended to cover the work in arithmetic of the fifth and sixth grades. The principles which have guided the authors may be grouped under three main heads: 1. Selection and Organization of Subject Matter. Recent discussion and practice, as revealed in the literature and in published curricula, seem to show substantial agreement as to what topics should be included in the earlier part of a course in Arithmetic, while there is yet considerable difference of opinion as to topics to be included in the later parts. All topics whose inclusion or exclusion is now being debated are placed among the supplementary topics at the end of Books Two and Three. The main body of each book furnishes a minimum course which may be studied without break in continuity. At convenient points in the text supplementary topics may be taken up. It is believed that in this respect these books will serve each of many different needs just as effectively as if they were prepared to meet such need exclusively. The business of the maker of text books is to furnish teachers and supervising officers effective instruments for carrying out their purposes, rather than to seek to impose rigidly his own personal predilections. It has been the purpose of the authors to arrange the subject matter in such manner that the greatest simplicity of treatment may be attained. In the third book this is exemplified by the consistent use of the pages 90, 103, 116. If the teacher thinks best, a symbol such as x may now be used to represent the unknown number. The development is so organized that this will not disturb the continuity in the slightest. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
