Hey 4th graders! Today, we’re diving into the world of super large numbers—numbers up to billions! You’ll learn how to compare these big numbers step by step and see that it’s just like comparing smaller numbers, but with more digits.

### What Are Numbers Up to Billions?

A billion is a massive number! It’s a 1 followed by nine zeros: 1,000,000,000. When we compare numbers up to billions, we’re looking at numbers that could have up to 10 digits or more. For example, 2,345,678,912 is a number in the billions.

### How to Compare Numbers Up to Billions

Comparing big numbers isn’t as hard as it seems. You just have to look at the place values, starting from the left:

**Look at the billions place.**If one number has more billions, it’s bigger. Simple as that!- Example: 5,123,456,789 is greater than 4,987,654,321 because 5 billion is more than 4 billion.

**If the billions place is the same,**move to the hundred millions place.- Example: 5,234,123,456 is greater than 5,123,987,654 because 2 hundred million is greater than 1 hundred million.

**Keep going place by place,**from millions to thousands, and so on, until you find a difference.

### Key Tip:

Always compare numbers from the left side first, where the biggest values are. Once you find a difference, you’ll know which number is greater.
