This document discusses comparing and ordering numbers. It explains how to compare numbers by lining them up based on place value and comparing the digits from left to right. Lower digits represent smaller values. It provides examples of comparing standard and word forms of numbers. The document also demonstrates how to order numbers from least to greatest or greatest to least by comparing place values from left to right and arranging the numbers in the appropriate order.

- 9. HOW TO COMPARE NUMBERS? LINE UP THE NUMBERS COMPARE AT THE HIGHEST PLACE VALUE (TENS) IF THE NUMBERS ARE THE SAME GO TO NEXT DIGIT TO THE RIGHT (ONES) 91 91 91 97 97 97 87 87 87
- 11. 91 < 97 > 87
- 12. fifty-six ___ 65 What about comparing a word form to standard form?
- 13. fifty-six < 65 What about comparing a word form to standard form?
- 15. 86 87 68 85
- 16. 86 68 < 85 > 87
- 17. A. 55>57<59 B. 57>55>59 C. 57<59>55 D. 55>57>59
- 18. A. 55>57<59 B. 57>55>59 C. 57<59>55 D. 55>57>59
- 21. ORDERING NUMBERS Lets put these numbers in order from least to greatest. 65 ; 72 ; 56 To put these in order, start in tens place. 65; 72 ; 56
- 22. ORDERING NUMBERS To put these in order, start in tens place. 65 ; 72 ; 56 Look at the 6, 7, 5. Out of those three numbers, which is the smallest?
- 23. ORDERING NUMBERS Look at the 6, 7, 5. Out of those three numbers, which is the smallest? The 5 is the smallest number, therefore 56 is the smallest number.
- 24. ORDERING NUMBERS Look at the 6, 7, 5. Out of those three numbers, which is the smallest? The 5 is the smallest number, therefore 56 is the smallest number.
- 25. ORDERING NUMBERS We see that 56 is the smallest number. Now let us compare 6 and 7. Which one of these two is smaller? 65; 72 ; 56
- 26. ORDERING NUMBERS Which one of these two is smaller? 65; 72 The 6 is the smallest number out of the two, thus 65 is the next smallest number in the set.
- 27. ORDERING NUMBERS We now know that 56 is the smallest number and 65 is the middle number. Therefore, which is the largest number? 65 ; 72 ; 56
- 28. ORDERING NUMBERS Therefore, which is the largest number? 65 ; 72 ; 56 72 is the largest number.
- 29. ORDERING NUMBERS Thus, the correct order of the set from least to greatest is 56 ; 65 ; 72
- 30. ORDERING NUMBERS What if we order them from greatest to least what would be the correct order? 56 ; 65 ; 72
- 31. ORDERING NUMBERS Greatest to Least Order: 72 ; 65 ; 56
- 33. LET US TRY THIS: Put these numbers in least to greatest order. 97, 92, 96
- 34. LET US TRY THIS: 92, 96, 97
- 35. LET US TRY THIS: Put these numbers in greatest to least order. 86, 98, 43, 54, 71
- 36. LET US TRY THIS: 98, 86, 71, 54, 43
- 37. Which set is in correct order from greatest to least? a. 28, 39, 51, 67, 74 b. 74, 67, 51, 39, 28
- 38. Which set is in correct order from greatest to least? a.28, 39, 51, 67, 74 b.74, 67, 51, 39, 28
- 39. Greatest to Least XV, LIII, XL
- 40. Greatest to Least LIII, XL, XV
