with three figures? What number is 1 more than 999? Beginning with 0, count by one thousand until nine thousand is reached. We write one thousand in this way: 1,000. Write two thousand, three thousand, four thousand, etc., to nine thousand. If we add 1,000 and 100, we have one thousand one hundred, which we write 1,100. Write two thousand three hundred. Write five thousand six hundred. If we add 1,000 and 10, we have one thousand ten, which we write 1,010. Write one thousand thirty. Write six thousand seventy. Write eight thousand eighty. Write one thousand one hundred ten. If we add 1,000 and 1, we have one thousand one, which we write 1,001. Write: One thousand four. Three thousand seventy-five. Two thousand six. Six thousand ninety-two. Eight thousand five. Five thousand six hundred seven. Four thousand nine. Two thousand five hundred forty. Nine thousand seven. Eight thousand ninety-seven. Write the following in figures: 1. Five thousand three hundred forty-seven. 2. One thousand eight hundred ninety. 3. Six thousand two hundred seven. 4. Eight thousand ninety-eight. 5. Two thousand four hundred. Do you know how to play the game of ring-toss? John, Mary, William, and Julia played one game and wrote their scores on a score card like the one in the picture. What was John's score? Mary's? William's? Julia's? What was their total score? What is the value of the 2 in the T column compared with the 2 in the O column? Write the scores without ruling the columns: What new figure must you use in writing William's score and Julia's score? Strike out the 0 in 240; what number remains? Strike out the 0 in 105; what number remains? What is the use of the 0 in writing a number like 240 or 105? In a number like 549, the right-hand figure (9) is in units' (or ones') place, the middle figure (4) is in tens' place, and the left-hand figure (5) is in hundreds' place. Each of these places is called an order; in a number of three figures, like 549, there are three orders, the order of units, the order of tens, the order of hundreds. In a number of four orders, like 7,549, the left-hand figure (7) is in the order of thousands. It is easier to read a large number if a comma is put between the hundreds' place and the thousands' place, e.g. 7,549; 6,280; 10,000. 7. Count by 10's from 10 to 100. 8. Count by 100's from 100 to 1,000. 9. Count by 1,000's from 1,000 to 10,000. Numbers to 100,000 COUNTING BY 1,000's To 20,000 We may count thousands as we count units: 1 thousand, 2 thousand, 3 thousand, 4 thousand, etc. 1. Count by thousands from 1 thousand to 20 thousand. 2. Write in a column the numbers you have counted; opposite each number, write the same number in words: e.g. One thousand Two thousand COUNTING BY 10,000's To 100,000 We may count ten-thousands as we count tens: 10 thousand, 20 thousand, 30 thousand, etc. 1. Count by ten-thousands from 10 thousand to 100 thousand. 2. Write in a column the numbers you have counted. |
