Bobbs-Merrill Arithmetics, Volume 1

This series of arithmetics makes a carefully planned attempt to combine the psychology of number-learning with the best experience of successful class-room practice. The principle employed is that the primary purpose of arithmetic is to put in the hands of the child a well-mastered tool for use in the practical affairs of his every-day living.
