Comparison helps us understand which number or group is bigger, smaller, or the same.
Real life examples:
> < =
> Greater Than — bigger number
< Less Than — smaller number
= Equal To — same number
Example 1: 9 is greater than 4
Example 2: 15 is greater than 8
Example 3: 9 stars > 4 stars
Example 4: 7 apples > 3 apples
Example 5: 28 is greater than 19
Example 6: 42 is greater than 35
Example 1: 6 is less than 11
Example 2: 13 is less than 20
Example 3: 3 stars < 6 stars
Example 4: 4 blocks < 7 blocks
Example 5: 25 is less than 38
Example 6: 17 is less than 29
Example 1: 10 is equal to 10
Example 2: 5 stars = 5 stars
Example 3: 22 is equal to 22
Example 4: 6 apples = 6 apples
Example 5: 45 is equal to 45
Smallest to Greatest (3 examples):
4, 9, 15 → 4 < 9 < 15
12, 27, 41 → 12 < 27 < 41
8, 19, 33, 50 → 8 < 19 < 33 < 50
Greatest to Smallest (3 examples):
50, 36, 21 → 50 > 36 > 21
45, 29, 14 → 45 > 29 > 14
38, 25, 17, 9 → 38 > 25 > 17 > 9
Example 1: You have 14 crayons. Your friend has 9 crayons.
14 > 9 → You have more crayons.
Example 2: There are 21 children in Class A and 21 children in Class B.
21 = 21 → Both classes have the same number of students.
Example 3: Your tower has 32 blocks. Your friend’s tower has 28 blocks.
32 > 28 → Your tower is taller.
Example 4: You counted 16 cars in the parking lot. Your mom counted 23 cars.
16 < 23 → Mom counted more cars.
Example 5: There are 47 stickers on your page and 47 stickers on your friend’s page.
47 = 47 → You both have the same number.
