While learning the Multiplication Table, the class may study to advantage the Lessons corresponding with its different parts, as in Addition and Subtraction.

Note. It is an interesting and profitable exercise, for young pupils, to recite tables in concert. But it will not do to depend upon this method alone. It is indispensable for every scholar who desires to be accurate either in arithmetic or business, to have the common arithmetical tables distinctly and indelibly fixed in his mind. Hence, after a table has been repeated by the class in concert, or individually, the Teacher should ask many promis. cuous questions, to prevent its being recited mechanically, from a knowledge of the regular increase of numbers.
