Publisher's Synopsis
Excerpt from Key to Ray's New Arithmetics, Intellectual and Practical
It may be supposed that every teacher is able to solve every example in the series; but it should not therefore be required that the work shall actually be done by the teacher. The examination to which every teacher in the Public Schools submits, is the only test that can be required of the possession of knowledge. In the actual work of the school-room, the teacher is clearly entitled to use all appliances that will save him from drudgery, and enable him to devote his full time and energies to the task of imparting instruction and guiding the labors of his pupils.
