Comparing Numbers up to 100

Do you remember what 2-digit numbers are? π€

** 2-digit numbers** have 1 digit in the **Tens place value** and 1 digit in the **Ones place value**.

For example, 54 and 89 are 2-digit numbers.

Is 100 a 2-digit number?Β

No. It's a 3-digit number!

Let's learn to compare 2-digit numbers using examples! π€

**Example 1: ****Compare 47 and 62.**

β
First look at the digits in the **Tens place**.

Which digit is bigger? π€Β

That's right! It's** 6**.

The number with thebigger Tens place valueis always greater.

So,Β

47is less than62

47<62

**Example 2:**** Compare 58 and 51.**

Do you remember the first step? You got it! π

β
First look at the digits in the **Tens place**.

Uh-oh! Both digits are equal. Now, what do we do? π€

β
When the tens place digits are equal, look at the **Ones place**.

Which digit is bigger? Good job! π **8**.

When the Tens place value is equal, the number with thebigger Ones place valueis greater.

So,

58is greater than51

58>51

**Example 3:**** Compare 43 and 43.**

You know the first step! Keep going! π€

β
First, look at the digits in the **Tens place**.

Are the digits equal? Yes they are! π

β
Then we look at the **Ones place**.

These digits are equal, too. π€

When two numbers havethe same Tens and Ones places, the numbers are equal.

So,

43is equal to43

43=43

When we compare two 2-digit numbers:

π The number with the **greater Tens place value **is always greater.

π If both numbers have the same Tens place value, the number with the **greater Ones place value **is greater.

π If both numbers have the **same Tens and Ones place values,** the numbers are equal.

Good work! Now, you can move on to the practice problems!
