BY EXCHANGE FROM NEW YORK STATE LIBRAR FEB 27 1932 REFACE. HILDREN obtain their first idea of numbers from the objects CHILDREN around them. In accordance with this law of development and growth of the young mind, the "object" method is freely used in the following pages. 1. The first ten numbers and their simple combinations are illustrated by pictures of visible objects. 2. The pupil from the first is taught to make figures, and to illustrate small numbers by unit marks. 3. As soon as a fact or principle is learned, he is taught its application and begins to practice it. 4. Oral and Slate Exercises are combined throughout the book. 5. Addition and Subtraction are taught in connection; being converse, the one is suggested by the other. For the same reason, Multiplication and Division are presented together. This is believed to be the best and most approved method of teaching these subjects. 6. The work is divided into Six Sections, and each Section into Twenty Lessons. The respective sections cover the ground required for promotion to corresponding Grades in the Primary Schools of New York, Brooklyn, and other large cities. These and other features of the book, it is hoped, will aid teachers in their work, and facilitate the progress of pupils in gaining a practical knowledge of this important study.
