1 Putting Numbers in Order From Greatest to Least From Least to Greatest

2 Greatest? Least? First we need to know the words. ZGreatest means biggest. ZLeast means smallest.

3 Look at Place Values ZLook at Tens and Ones ZOne digit numbers are smaller. 0-9 ZTwo digit numbers are bigger

4 One Digit Numbers The numbers are smaller. We only see them in the ones place. Tens ones

5 Two Digit Numbers The numbers are bigger. We see them in the ones and tens places. TensOnes

6 Choose The Greatest Tensones 5 Tensones 35 or Tensones 79 Tensones 9 or

7 Choose the Least Tensones 73 Tensones 4 or Tensones 9 Tensones 26 or

8 Ordering 2-Digit Numbers First: Compare the tens place. The number with the bigger digit is the greatest number. Next: If the tens place is the same, compare the ones place. The bigger digit in the ones place is the greatest number. Tensones Tensones

9 Lets Practice Put these numbers in order from least to greatest. (smallest to biggest) They can be put in order by looking at the tens place only

10 Lets Try a Harder One Look at the tens place. I know 11 is least because it has a 1 in the tens place. I know 42 is greatest because it has a 4 in the tens place Look at the ones place for 38 and 35. A 5 is smaller than an 8, so 35 comes before 38. Order these numbers from least to greatest.

11 More Practice… Put these numbers in order from least to greatest. Look at tens, then look at ones
