This primary work is designed for small children, and as an easy introduction to the “ Progressive Intel- lectual Arithmetic,” for advanced classes. Its object is to lead the young pupil, by brief and simple processes, applied to practical examples of easy gradation, to acquire habits of thought and of reasoning, in their simplest forms, and to draw out and strengthen the mind by a progressive and almost imperceptible gra- dation of thought and expression. The operations of Adding and Subtracting, of Multi- plying and Dividing, are first shown by pictorial objects; portions of the elementary tables are introduced at the commencement of each lesson, and applied to short ex- amples concerning familiar objects; promiscuous reviews of the elementary tables, and the more simple and easy Denominate tables have been introduced. Fractions have been treated as far as was thought practicable in a work of this kind. It is confidently believed that the progressive and systematic arrangement, the simplicity and adaptation to the juvenile mind, the typography and general attrac- tiveness of this little book, will insure for it abundant success. THE AUTHOR. (3) 3 ke SUGGESTIONS TO TEACHERS. 1. A TEACHER should have a particular time allotted to every exercise, and regular lessons should be assigned, to be recited each day at a specified hour. 2. Sufficient time being given the pupils to learn their lessons, they should not be allowed the use of the book at the time of recitation. 3. The teacher should first ascertain that the table is thoroughly learned by every pupil in the class. 4. Each question should be slowly and distinctly read, and the pupils be called upon promiscuously; the pupil called upon should stand erect, repeat the question, and then give the solution. This will require close attention. 5. A correct and uniform analysis of each question should be required from every pupil. 6. The class should be encouraged to detect and cor- rect errors in the statement and solution of questions, to be signified by raising the hand. 7. The teacher can extend the questions in each les- son at pleasure, either by repeating those given, or making additional ones. (4) 03/ PRIMARY ARITHMETIC. LESSON I. 1.
