ARITHMETICS BOOK TWO BY GEORGE MORRIS PHILIPS, LL.D. PRINCIPAL, WEST CHESTER, PA., STATE NORMAL SCHOOL; FORMERLY PREFACE Book Two of the Silver-Burdett Arithmetics has been prepared for grades five and six. Part One, intended for the fifth grade, emphasizes fundamental operations and Common Fractions; it gives an elementary treatment of Decimals through thousandths, and of Denominate Amounts. Part Two, intended for the sixth grade, reviews fundamental operations, reviews and extends the work of the fifth grade in Common Fractions, treats as fully as conditions demand, the subjects of Decimals, Denominate Amounts, and Practical Measurements, and presents enough of the elementary facts of Percentage to give pupils who leave school at the close of the sixth year, a practical idea of Profit and Loss, Trade Discount, Commission, Interest, the Promissory Note, the Check, and the Receipt. Attention is invited to the following features of the book: 1. The abstract problems for developing accuracy and speed; and the well-graded, concrete problems, free from puzzling conditions, for securing mental discipline and for bringing the child into closer touch with the affairs of modern life. iii 304079 2. The development, through simple diagrams, of the important principles of Fractions, and the sight drills for fixing these principles. 3. The prominence given to Decimals to the end that pupils may become proficient in a subject so extensively used later, both in school and in business. 4. The model solutions of prominent types of problems, so arranged as to encourage pupils to present their work in neat form, thus assisting the teacher in her effort to correct the many inaccurate expressions in common use. 5. The frequent and extended Reviews which afford abundance of problem material for large classes. |
