We are quite familiar with number lines now. Let’s see if we can place some numbers in their appropriate positions on the number line. Here are the numbers: 2180, 2754, 1500, 3600, 9950, 9590, 1050, 3050, 5030, 5300 and 8400.

Question

Accepted Answer

First decide which pair of thousands each number lies between, then place it nearer the left or the right mark: Number Lies between Where exactly 1050 1000 and 2000 just after 1000 1500 1000 and 2000 exactly halfway 2180 2000 and 3000 a little after 2000 2754 2000 and 3000 closer to 3000 3050 3000 and 4000 just after 3000 3600 3000 and 4000 a bit past halfway 5030 5000 and 6000 just after 5000 5300 5000 and 6000 nearer 5000 8400 8000 and 9000 a little before halfway 9590 9000 and 10,000 just past halfway 9950 9000 and 10,000 almost at 10,000 1000 2000 3000 4000 5000 6000 7000 8000 9000 10,000 1050 1500 2180 2754 3050 3600 5030 5300 8400 9590 9950 All eleven numbers marked on the number line. Numbers like 1050, 3050 and 5030 sit very close to a thousands mark; 1500 is exactly in the middle of 1000 and 2000. Tip: to place a number, first look at its thousands digit — that fixes the pair of marks. Then look at the hundreds digit to see how far along to go: 3600 has 6 hundreds, so it goes a little past the middle of 3000 and 4000.

Number	Lies between	Where exactly
1050	1000 and 2000	just after 1000
1500	1000 and 2000	exactly halfway
2180	2000 and 3000	a little after 2000
2754	2000 and 3000	closer to 3000
3050	3000 and 4000	just after 3000
3600	3000 and 4000	a bit past halfway
5030	5000 and 6000	just after 5000
5300	5000 and 6000	nearer 5000
8400	8000 and 9000	a little before halfway
9590	9000 and 10,000	just past halfway
9950	9000 and 10,000	almost at 10,000
