Hey there! Today, we’re going to learn about rounding numbers. It’s like a fun game where we make numbers simpler and easier to use. Let’s dive in and see how it works!
Rounding is a way to change a number to a nearby number that ends in zero. We do this to make numbers easier to work with. For example, if you have 175, you can round it to 200. Cool, right?
To round a number to the nearest hundred, we need to look at the tens place. Here’s how you do it:
Imagine a park ranger wants to know how many people visited some famous places. Let’s help her by rounding the numbers!
175 people visited Mount Rushmore. Let’s round this number to the nearest hundred:
Old Faithful had 871 visitors. Let’s round this number:
The Grand Canyon had 963 visitors. Let’s round this number:
Always look at the place to the right of the place you want to round to. If it’s 5 or more, round up. If it’s 4 or less, round down. Easy peasy!
Thanks for learning with us! Keep practicing, and you’ll be a rounding expert in no time. See you next time!
Rounding Number Hunt: Go on a number hunt around your house or classroom! Look for numbers on clocks, books, or even food packages. Write down three numbers you find and practice rounding them to the nearest hundred. Share your rounded numbers with a friend and see if they agree with your rounding!
Rounding Relay Race: Gather a group of friends or classmates and form two teams. Each team gets a set of number cards (e.g., 243, 567, 892). The goal is to round each number to the nearest hundred as quickly as possible. The first team to correctly round all their numbers wins! This activity helps you practice rounding quickly and accurately.
Everyday Rounding: Ask an adult to help you find a grocery store receipt. Look at the prices and choose three items. Round the prices to the nearest hundred and add them up. Compare the total with the original prices. Discuss with your adult how rounding can make adding numbers easier and faster!

Welcome to Kids Academy! If you want to round a number to the nearest hundred, you need to look at the tens place to decide whether to round up or down. I like to underline the place I’m rounding to, which is the hundreds place, and draw an arrow to the tens place.
You always look one place to the right of the place you want to round to. In this case, we’re rounding to the nearest hundred, so we’ll look at the tens place. The same rule applies when rounding to the hundreds place as it does when rounding to the tens.
The key number is five: if it’s five or higher, you round up; if it’s four or lower, you round down. You round the number in the hundreds place and make the numbers in the ones and tens places zeros.
Let’s look at a real-life situation that requires rounding and see how our rounding skills can come in handy. This park ranger wants to record how many people visited these national landmarks by rounding to the nearest hundred.
Let’s help her by rounding. First, we’ll check out Mount Rushmore, one of my favorite landmarks. According to the data, 175 people have visited Mount Rushmore. Now, let’s round that number to the nearest hundred.
We’ll use the strategy of underlining the hundreds place and drawing an arrow to the tens place. I see a seven in the tens place. Since it’s five or higher, we round up. The one in the hundreds place is underlined, so we’ll round one hundred up to two hundred. When rounding to the hundreds place, the numbers in the tens and ones places become zeros.
Now, I have a challenge for you! Help the ranger round the next two landmarks’ visitors to the nearest hundred. Take your time to think, and if you need more time, you can pause the video.

Okay, here’s the answer: Old Faithful had 871 visitors. We’ll use the same strategy of underlining the hundreds place and drawing an arrow to the tens place. I see a seven in the tens place, so we round up. The eight in the hundreds place is underlined, so we round up eight hundred to nine hundred. When rounding to the hundreds place, the numbers in the tens and ones places become zeros.
Next, we have the Grand Canyon with 963 visitors. Again, we’ll underline the hundreds place and draw an arrow to the tens place. I see a six in the tens place, so we round up. The nine in the hundreds place is underlined, so we round up nine hundred to one thousand. When rounding to the hundreds place and rounding up to a thousand, the numbers in the hundreds, tens, and ones places become zeros.
Remember to look at the place to the right of the place you want to round to, and round up if you see a five or higher.
