Rounding Decimals & Whole Numbers Song

“The number to the right must be found:
Five or more? ROUND UP! Less than five? ROUND DOWN!”

This video is the alternative to the Numberock's Rounding Whole Numbers Song. In this version of the song, Numberock drops underwater just off the coast of a major seaport to compare and round decimals in lieu of their whole number contemporaries featured in our other video featuring ONLY whole numbers.

Rounding Numbers Song Lyrics:

When rounding to a certain place value,
Find the rounding place, then continue to
Look at the number to the right; man, you don’t need luck.
If the digit’s five or more, then round up.
If the digit’s less than five, then round down.
That’s how the rounded number is found.

When rounding up, the rounding place goes up by one.
When rounding down, it stays where it had begun.
The numbers to the right of the rounded digit
Get changed to zeros; then it’s legit.

When you need to find out an approximate amount,
Rounding gives you numbers that are easy to count!

When rounding to a decimal place value,
Find the rounding place, and then continue...
The process to round decimals is the same.
You just need to know the place value names.
The number to the right must be found:
Five or more? ROUND UP! Less than five? ROUND DOWN!

When rounding up, the rounding place goes up by one.
When rounding down, it stays where it had begun.
When you round decimals, you can erase
What’s right of the rounded digit’s place.

Here’s a trick to use... to help you choose
Where the digit to the right tells you to move.
Draw zero to ten on a hill, with five on top.
A car drives until it comes to a stop.
If it’s five or more, it moves forwards.
If it’s one through four, it moves backwards.
Forward rounds up; backward rounds down;
Just a little trick to help you round!
