2. 2. Compare Numbers <ul><li>Compare 34,693 and 34,539 </li></ul><ul><li>Compare ten thousands (start from left and go right) </li></ul><ul><li>3 4,693 same </li></ul><ul><li>3 4,539 </li></ul>
3. 3. Compare Thousands <ul><li>Compare 34,693 and 34,539 </li></ul><ul><li>Compare thousands </li></ul><ul><li>3 4 ,693 same </li></ul><ul><li>3 4 ,539 </li></ul>

5. 5. So… <ul><li>Compare 34,693 and 34,539 </li></ul><ul><li>So 34,693 > 34,539 </li></ul>
6. 6. Let’s Practice! <ul><li>Start at the left. Name the first place-value position where the digits differ. Circle the greater number. </li></ul><ul><li>146, 7 36 146, 8 46 </li></ul><ul><li>hundreds </li></ul><ul><li>49,872 48,871 </li></ul><ul><li>107,198 107,189 </li></ul><ul><li>17,612 20,176 </li></ul>

9. 9. Order the Numbers <ul><li>Order the numbers from least to greatest </li></ul><ul><li>432,220 432,170 432,220 </li></ul><ul><li>Remember to start from the left and compare! </li></ul>
10. 10. Now, you try it! <ul><li>46,464 46,644 46,466 </li></ul><ul><li>2. 53,149 45,871 42,193 </li></ul><ul><li>3. 197,197 179,179 197,917 </li></ul><ul><li>4. 481,564 87,781 487,763 </li></ul>
11. 11. Now, order from greatest to least <ul><li>Order these numbers from greatest to least </li></ul><ul><li>246,736 246,846 246,856 </li></ul><ul><li>78,232 78,233 78,332 </li></ul><ul><li>94,675 97,537 97,735 </li></ul>

13. 13. More on Rounding Numbers <ul><li>Round to the nearest hundred </li></ul><ul><li>12, 3 76 </li></ul><ul><li>The number to the right of “3” is “7” </li></ul><ul><li>7 is greater than 5, which means that I need to round the 3 up to a 4 </li></ul><ul><li>All numbers after the 4 will become a 0 </li></ul><ul><li>The answer is 12,400 </li></ul>
