**What is Comparing?**

Comparing means to know if one number is the same as, or smaller than, or bigger than, another number.

**How do we compare numbers?**

To compare numbers, we look at the value of digits.

For example,

We start comparing numbers from the highest value column i.e., from the left-hand side.

27 have 2 tens and 59 have 5 tens.

So, 59 is bigger than 27.

**What if the tens are the same?**

If the tens are the same, we’ll compare the next value column i.e., ‘ones’.

58 and 54 have 5 tens each. So, we’ll look at the ones digits now.

58 has ‘8 ones and 54 has ‘4 ones.

So, 58 is bigger than 54.

**Comparing numbers using a number line**

We can also use number lines to compare two numbers.

**For example,**

The number on the right side of a number line is always bigger than the number on the left side.

So, 31 is bigger than 27.

**Symbols**

We use 3 symbols to compare numbers.

**What is Ordering?**

Ordering means arranging in a sequence.

There are two ways of ordering:

**Ascending**: Smallest to biggest**Descending**: Biggest to Smallest

**Example:** Order the numbers 28, 83, and 75 in ascending and descending order.

**21** has 2 tens

**83** has 8 tens

**75** has 7 tens

**Ascending order** i.e., smallest to biggest is 21, 75, 83

**Descending order** i.e., biggest to smallest is 83, 75, 21
