3. Find your number Find your number Look right next door Look right next door 4 or less just ignore 4 or less just ignore 5 or more, add 1 more 5 or more, add 1 more Everything after is a zero, Everything after is a zero, no more no more

4. What is rounding? Rounding means changing a given number to the nearest ten, hundred, thousand, and so on. Numbers can be rounded to the nearest ten, the nearest hundred, the nearest thousand, and so on.

5. To round a number to a given place: Find your numberStep 1: Find your number circle Find the place you are rounding to: ten, hundred, thousand or another place value and circle it. ie: Round 6,438 to the nearest hundred H thT thThHTO 6438

6. Look right next door (Step 2: Look right next door ( Look at the digit to its right) and underline it. H thT thThHTO 6438

7. H thT thThHTO 6438 H thT thThHTO 6400

9. To round a number to a given place: Find your numberStep 1: Find your number circle Find the place you are rounding to: ten, hundred, thousand or another place value and circle it. ie: Round 6,458 to the nearest hundred H thT thThHTO 6458

10. Look right next doorStep 2: Look right next door ( ( Look at the digit to its right) and underline it. H thT thThHTO 6458

11. 5 or more, add 1 more 5 or more, add 1 more If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. (add 1 to the number in the circle) ie: Look in the ten place of the number 6,458. We see a 5, so we must add 1 to the number in the circle. H thT thThHTO 6458 4+1 = 5 H thT thThHTO 65

12. H thT thThHTO 6500

13. ten  Round 13,528 to the nearest ten. 13,5288 > 5 up Round up 13,530to 13,530 hundred  Round 13,528 to the nearest hundred 13,5282 < 5 down Round down 13,500to 13,500. thousand  Round 13,528 to the nearest thousand. 13,5285=5 up Round up 14,000to 14,000 All the numbers to the right of the place you are rounding to become zeros.

16. You can use a number line to round a whole number to a given place. 2,683 Round 2,683 to the nearest hundred. First, find the rounding place. 2683 Hundreds

17. Then, find the number on a number line. 2,683 is between 2600 and 2,700

18. Round the number to the closest hundred on the number line. 2,700 is the closest hundred. Round 2,683 up to 2,700.

19. Hint: If a number is located directly in the middle of the number line, round up.

20. Consider the number 4,827. – 4,827 rounded to the nearest ten is 4,830 – 4,827 rounded to the nearest hundred is 4,800 – 4,827 rounded to the nearest thousand is 5,000 Here are some more examples: – 34 rounded to the nearest ten is 30 – 6,809 rounded to the nearest hundred is 6,800 – 1,951 rounded to the nearest thousand is 2,000

21. Rounding is a form of estimation that you use when an approximation is good enough. For example when you are buying a TV at the store. The cost might be marked at $279.00. You could say it is about $300.00. Rounding is also good to use so that you know what to expect for an answer. It is good to use this skill when you are plugging numbers into a calculator. Ex. Let's say you are adding up your expenses for the month. Power: $230, Telephone: $79.68 Rent: $470 Car Payment: $822. To get a good approximation of the money you will need you could round to the closest hundred: Power: $230 would be$200 Phone $79.68 would be $100 Rent: $470 would be $500 Car: $822 would be $800 Total: $1601 which is close to the estimated total of $1600
