I FUNDAMENTALS OF HIGH | 



I SCHOOL MATHEMATICS | 



I An Efoch-making Textbook Designed to Follow Arithmetic \ 



I By Harold O. Rugg and John R. Clark | 



I ' I ■• HE authors have assembled in this ninth-grade | 



I A course the most important mathematical tools and | 



I notions which all children should know. The excessive | 



I manipulation of symbolisms of formal algebra has been | 



I replaced by material which is, both from the mathematical | 



I and social point of view, of far greater value. Specific- | 



I ally, graphs, methods of direct and indirect measurement, | 



I the properties of the right triangle, and a comprehensive j 



I treatment of the concept of relationship betiueen changing | 



I quantities (i. e., functionality) have replaced the elaborate | 



I treatment of factoring, fractions, and operations with long | 



I polynomials. | 



I The selection of material for this course is quite in agree- j 



I ment with the recommendations of the National Commit- | 



I tee on Mathematics Requirements. The authors have | 



I sensed fully the best thought of the day in the reorgani- | 



I zation of first-year high school mathematics courses. | 



I Among the unique impressions made upon the reviewer, | 



I the following stand out most prominently: j 



I 1 The careful explanations and development of | 



I new processes; 1 



I 2 The wholesome omission of formal material ; | 



I 3 The excellent presentation of word-problems; | 



j 4 The unique organization of special products 1 



I and factoring; | 



I S The "timed practice exercises" for developing | 



I skill in essential tool processes; and | 



I 6 The emphasis upon the notion of relationship | 



I between variable quantities. |
