Compare, Order, and Round Whole Numbers
- 1. Compare, Order, and Round Whole Numbers Mrs. Young EMC 1
- 2. Compare Numbers Compare 34,693 and 34,539 Compare ten thousands (start from left and go right) 3 4,693 same 3 4,539
- 3. Compare Thousands Compare 34,693 and 34,539 Compare thousands 3 4 ,693 same 3 4 ,539
- 4. Compare Hundreds Compare 34,693 and 34,539 Compare hundreds 3 4 , 6 93 6 > 5 3 4 , 5 39
- 5. So… Compare 34,693 and 34,539 So 34,693 > 34,539
- 6. Let’s Practice! Start at the left. Name the first place-value position where the digits differ. Circle the greater number. 146, 7 36 146, 8 46 hundreds 49,872 48,871 107,198 107,189 17,612 20,176
- 7. Compare Use <, >, or = to compare. 345 354 4,758 4,578 13,344 14,433 583,583 583,583 565,565 565,656
- 8. Now, let’s order numbers! Use the same rule for comparing to be able to put numbers in order from least to greatest Start from left to right to determine which place values differ.
- 9. Order the Numbers Order the numbers from least to greatest 432,220 432,170 432,220 Remember to start from the left and compare!
- 10. Now, you try it! 46,464 46,644 46,466 2. 53,149 45,871 42,193 3. 197,197 179,179 197,917 4. 481,564 87,781 487,763
- 11. Now, order from greatest to least Order these numbers from greatest to least 246,736 246,846 246,856 78,232 78,233 78,332 94,675 97,537 97,735
- 12. How do I round numbers??? Rounding Numbers Look at the digit to the right of where you are rounding If the digit is 4 or less, round down If the digit is 5 or more, round up Round to the nearest hundred 6, 7 28 The number to the right of the 7 is a 2 2 is less than four so I need to round down! 6,728 rounded to the nearest hundred equals 6,700
- 13. More on Rounding Numbers Round to the nearest hundred 12, 3 76 The number to the right of “3” is “7” 7 is greater than 5, which means that I need to round the 3 up to a 4 All numbers after the 4 will become a 0 The answer is 12,400
- 14. Rounding Numbers continued… Round to the nearest hundred 4, 0 82 The number to the right of 0 is 8 8 is greater than 0, which means that I need to round the 0 up to a 1 All numbers after the 1 will become a 0 The answer is 4,100
- 15. You try it! Round to the nearest thousand 4 ,817 1 1 , 9 62 3 5 , 6 32 1 6 ,498
