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.

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
