Comparing numbers

Students will learn how to compare two or more numbers using symbols like:

  • Greater than ( > )
  • Less than ( < )
  • Equal to ( = )

Place Value Helps Compare Numbers:

  • First compare the number of digits.
  • If the numbers have the same number of digits, compare the place values (start from the left).
Example:

  • 453 and 672 β†’ Compare hundreds: 4 < 6 β†’ So, 453 < 672

Comparison Symbols:

  • > means greater than
    Example: 89 > 45
  • < means less than
    Example: 23 < 78
  • = means equal to
    Example: 99 = 99

  • Think of the greater than ( > ) symbol as a crocodile mouth:
    πŸ‘‰ The crocodile always eats the bigger number! Example:
    78 ___ 45 β†’ 78 is greater, so the crocodile eats 78 β†’ 78 > 45
  • Line up digits by place value (hundreds, tens, ones) when comparing.

Number 1Number 2SymbolComparison
325512<325 < 512
740407>740 > 407
999999=999 = 999
8708700<870 < 8700

  1. 426 ___ 412
  2. 999 ___ 1000
  3. 678 ___ 678
  4. 53 ___ 35
  5. 8,123 ___ 8,213

A number line helps to see which number is larger.
πŸ‘‰ Numbers to the right are greater
πŸ‘‰ Numbers to the left are smaller


  • Compare – to look at two numbers to see which is bigger or smaller
  • Greater than ( > )
  • Less than ( < )
  • Equal to ( = )
  • Place value

Tip

Imagine the symbols are an alligator’s mouth. The alligator always eats the bigger number!

First, the number 856, then the mouth of an alligator opening to the left in the shape of a greater-than sign, then the number 829. Second, the number 3,547, then the mouth of an alligator opening to the right in the shape of a less-than sign, then the number 3,582. Third, the number 10,503, then a face-on view of alligator's mouth in the shape of an equal sign, then the number 10,503 again.

40 ____ 36.

  • is greater than
  • is less than
  • is equal to
  • When you count, 40 comes after 36.
  • 40 is greater than 36.

39 ____ 7.

  • is greater than
  • is less than
  • is equal to
  • When you count, 39 comes after 7.
  • 39 is greater than 7.

83 ____ 83.

  • is greater than
  • is less than
  • is equal to
  • The number 83 is on both sides. Both sides are equal.
  • 83 is equal to 83.
