Excerpt from Graded Work in Arithmetic
This book is designed to complete a well-graded and comprehensive grammar school course in arithmetic.
It begins. With a review of the essential parts of the lower books, and then furnishes a thorough treatment of further applications of percentage and interest required in the grammar school course. It includes also exercises on the metric system, the elementary principles of algebra, involution, evolution, and mensuration, besides a number of special problems on work, time, temperature, specific gravity, etc.
Like the other books of the series, this book is largely based on the inductive method of teaching.
Great care has been taken in the selection of illustra tive examples. Operations, explanations, and analyses have been given in full, in order that the principles in volved may be easily and clearly understood by the pupil with but little assistance from the teacher.
