This textbook is a second-grade course in arithmetic. While it contains a review of the work of Grade I, pupils who have not had the benefit of a kindergarten training or of Grade I drill will need to have certain principles and definitions more carefully explained. Starting with this knowledge, which is usually given in all Kindergartens, the work in this grade advances logically, as the mind of the child expands. One or more lessons are given to the developing of a new topic; then the following lessons are so arranged as to give the pupils practice in applying the new topic in connection with all the other topics previously learned. This constant review will be found very beneficial.
