Concrete Geometry for Beginners. By 



A. R. Hornbrook, A.M., Teacher of Mathematics in 



High School, Evansville, Ind. 



Linen, i2mo, 201 pages. Price, 75 cents. 



This little work has been prepared by a practical 

 teacher of mathematics as an elementary text-book for 

 beginners in the study. In scope, plan and grade, it is 

 adapted to follow the course in mathematics usually pur- 

 sued in Common and Grammar Schools, or to precede the 

 study of Demonstrative Geometry in the High School. 



Some of the distinctive methods illustrated and applied 

 in the book are the following: 



Experimental Work. The work is eminently practical, its material 

 and methods being the results of actual experimental work in private and 

 public schools in discovering the effects produced upon the minds of 

 pupils by mathematical instruction, and in seeking to adjust such instruc- 

 tion to the mental capacity of the pupils, so that it may be most readily 

 assimilated and understood by them. 



Rational Development. This little book, without giving rules to be 

 learned or formal modes of reasoning to be copied, leads the child to 

 construct, to observe, to compute, to infer for himself and to report the 

 result of his operations in mathematical language. 



Progressive Plan. The plan of the book is to follow the method of 

 gradually developing each subject by questions, giving necessary infor- 

 mation and directions in notes, thus allowing full scope to the skilful 

 teacher who can expand the subjects and adjust the material to the special 

 needs of each class. 



Laboratory Methods. The use of this convenient text-book for a few 

 weeks before taking up Demonstrative Geometry, will give a class that 

 familiarity with geometric forms and facts which is essential to logical 

 reasoning, and will thus greatly increase the chances of rapid and suc- 

 cessful work. The great number of problems and their very gradual 

 increase in difficulty, admirably adapt the work for use by the Laboratory 

 Method.
