Excerpt from Sheldons Elementary Arithmetic: With Oral and Written Exercises Sheldon's Elementary Arithmetic is the first of two-book series published to meet the demands of progressive teachers. The teachers of primary arithmetic have recently made such rapid and extensive advances in the methods employed as to create, by the variety and novelty of many of these methods, a sense of uncertainty in the minds of the teachers themselves. From so much that is novel, it has been the aim of the publishers of this series to select that which is acknowledged to be a substantial improvement, and to so arrange the matter in two books, that the more progressive work in the lower primary grades may be quite in harmony with the more conservative work in the higher grades. In the preparation of this Elementary Arithmetic, special attention has been paid to the laws for the development of the faculties of the mind. The powers of observation have been encouraged, by the use of objects and pictures, and by reference in the problems to the arithmetic of nature, as shown in some of the smaller, yet common forms of plant and animal life. The combinations of numbers have been impressed upon the memory by constant, yet as far as possible, unconscious repetition. The judgment of the pupil has been called into exercise, not only by the methods of comparison, but by the contrasts afforded by blending with the otherwise monotonous work of the elementary rules, the simplest exercises under the next higher rules.
