1. Read the number on the blackboard. 2. In 376, for what does the 6 stand? the 7? the 3? 376 3 hundreds, 7.tens, 6 ones. = 3. Read 3498. For what does each figure stand? Each figure has a value that depends on its place in the number. The first place beginning at the right of a number is called ones' place; the second, tens' place; the third, hundreds' place; the fourth, thousands' place, etc. 4. Show that the left-hand 5 in the number 555 has a value, because of its place, that is 10 times the value of the middle 5, and 100 times the value of the right-hand 5. A number containing more than four figures is often separated, for convenience in reading, into groups, or periods, of three figures each, beginning at the right. The name of the first period is units; of the second period, thousands; of the third period, millions. The number on the blackboard above shows the arrangement of periods, and the three orders of figures in each. |
