Study the above pictures. Do we first compare how many TENS the numbers have or how many ONES the numbers have?
- Compare first how many ________ the numbers have.
- If the numbers have the same amount of _______, then compare the ________.
For example,
-
92 has more TENS than 89. Therefore 92 is greater than 89.
- 62 has the same amount of TENS as 66, but it has less ONES than 66. Therefore 62 is less than 66.
The symbol > means "greater than", and
< means "less than".
The open end or open mouth of the symbol ALWAYS points to the bigger
number.
For example,
|
3 < 5 |
14 > 3 |
60 > 50 |
48 < 99 |
7 < 17 |
You can also use the number line for help.
Since 44 comes before 47 when you read the number line from left to right, 44 < 47.
Example problem types
1. For each number, draw sticks to represent the tens and dots to represent the ones. Then write either < or > in between the two numbers.
