Nole. The process of adding and the structure of the Table may be easily illustrated by the Numerical Frame. Thus, to show that five and four make nine, move out five balls on one wire and four on another, and let the pupil count them together. But as soon as the pupil understands the principle of the operation, he should then learn to perform it without the

SECTION III.

SUBTRACTION.

LESSON I.

1. Suppose I have two peaches, and give one of them away, how many shall I have left!

Solution-One peach taken from two peaches, leaves one. Therefore if I have two peaches and give one of them away, I shall have one left.

2. Open three fingers on your left hand; now if you shut one of them, how many will remain open? One taken from three leaves how many?

3. George having four marbles in his hand, dropped one of them: how many had he left?

Note. The principle of subtracting one number from another, may be easily explained to the pupil by the Numerical Frame. Thus, to show how many three taken from eight will leave, move across eight balls, then moving three of them part way back, let the pupil count those that are left.

4. Leonard had five cents and gave one for a pencil: how many cents had he left? One from five leaves how many
