Excerpt from Efficiency Arithmetic Advanced
This book has been prepared in the belief that work in Arithmetic in the seventh and eighth grades should emphasize drill upon fundamentals and their application to living, vital problems that the average child is almost sure to encounter in his individual experiences. At the same time, it is recognized. that for the great majority using the books of this series certain topics will never receive consideration in the school training. unless presented in this volume. Great care has been taken to present these topics in a simple, clear manner which ought to cl make their meaning and significance intelligible even to the younger pupils.
The problems of the book, almost without exception, are actual problems taken from the various lines of business represented. Business men from all sections of the country have contributed problems, furnished definite and accurate information upon which to base problems, and have criticized the work from the standpoint of practical efficiency and reliability. Acknowledgment is hereby made to these gentlemen for their invaluable assistance.
The methods of presentation and explanation of topics new I to the child have been carefully tested in the school room and their effectiveness is thereby assured. Simplicity, clearness, and the avoidance of unnecessary repetition we believe to be characteristic of this series, especially in the applications of percentage and practical measurements which so often unnecessarily confuse the pupil.
Many school systems are modifying their courses in mathemathics in order to permit elementary algebra to be commenced in the eighth grade.
