At a barbecue to celebrate the end of the soccer season, 1,354 hotdogs were served. Let me just rewrite the number as 1,350 for now. Let's remember the different place values: ones, tens, hundreds, and thousands. Now, they want to round the number of hotdogs to the nearest ten. We currently have five tens. However, in order to round, we have to look at the next smallest place, which is the ones. We have four ones, and since this number is less than five, we round down. So, we have rounded to the nearest ten, which is 1,350 hotdogs. Let's try another example. The attendance at a local basketball game was 8,643. We need to round the attendance to the nearest hundred. To do this, we look one place to the right, and since the number is less than five, we round down. Therefore, the attendance is rounded to 8,600 people. Now, let's do one more. The city of Joy Ville has 87,388 residents. We want to round the number of people who live in Joy Ville to the nearest thousand. Again, we look one place to the right and see that it is less than five. Therefore, we round down to 87,000, which is the nearest thousand. In all the examples, we rounded down. However, let me show you what would happen if we rounded up. If the number was 87,588, and we wanted to round to the nearest thousand, we would look one place to the right and see that it is five or greater. In this case, we would round up, and the thousands would become 88,000. So remember, if the number is less than five, we round down, but if it is 5 or greater, we round up.
