Excerpt from Junior High School Mathematics Third Course This book has been planned to meet the needs of the first year mathematics in the ordinary high school, as well as to serve as a Third Course in Junior High School Mathematics. Comparison with the traditional freshman course in ordinary high schools, will show that certain geometric matter of admitted value has been inserted, and some relatively useless topics have been omitted from the algebraic portions. This renders the book particularly suitable for use as a freshman text in mathematics in ordinary high schools, and it does not detract from its value as a Third Course in Junior High School Mathematics. The review of arithmetic and of elementary geometric and algebraic notions, with which the book begins, is very desirable for any course of this type; and it makes the work usable either with or without the preceding books in the series. The authors have been guided in their work by the following principles: 1. That there should be a high degree of continuity in the subject matter of mathematics and in the methods of presenting it during the three years of the Junior High School.
