Comparing numbers

Comparing numbers

Comparing numbers is a skill you will need almost every day.

It is really important when you are using money to buy something.

You have to understand place value in order to compare numbers.

In 3rd grade you have to be able to compare numbers in the thousands.

Let's look at the number 4,357. The 4 is in the thousands place, the 3 is in the hundreds place, the 5 is in the tens place, and the 7 is in the ones place.

Let's look at that number again.

4,357

The value of the 4 is 4000, the value of the 3 is 300, the value of the 5 is 50 and the value of the 7 is 7.

In the number 4,453 the value of the first 4 is 4000, the value of the second 4 is 400, the value of the 5 is 50 and the value of the 3 is 3.

Now look at both of the numbers together.

4,357

4,453

I want to know which one is greater. First I look at the 1000's place. They are the same. Then I look at the 100's place and I see that one number has a 4 and one has a 3. Since 400 is greater than 300, I know that 4,453 is greater than 4,357.
