BELFIELD, AUTHORS OF MODEL ARITHMETIC, ETC. CHICAGO: GEO. SHERWOOD & CO. PREFACE. THIS book is designed both as an introduction to the Model Arithmetic, and as a text-book of sufficient comprehensiveness for those who do not complete the full grammar-school course. It has been the aim of the authors to present in it the accuracy of statement, clearness in discussion, and fullness of illustration, which are believed to characterize their larger work. The matter, aside from definitions, etc., is new, and has been tested in the school room. The introduction will be found of great use, not only in developing the idea of number, but in affording material for constant drill in fundamental operations. Among the features which distinguish the book from many of its class, will be noticed the absence of pictures of common objects. No space is wasted in representing, by the engraver's art, that which every teacher presents to the eye of the pupil. Teachers every-where recognize the fact that the object itself is better than the picture of it; that, for instance, the actual division of an apple into halves, quarters, etc., in the presence of a class, produces a clearer and more lasting conception of the idea of a fraction, than is secured by any picture, however perfect. The work, though elementary, is not designed as a plaything, but is an earnest attempt to assist in training the child's mind, and in fitting him for active life. As such, it is commended to the public. Chicago, April, 1876. KARVARD COLLEGE Den 19147 LIBRARY COPYRIGHT, 1876, BY GEO. SHERWOOD & CO, K. & B. |
