Rounding Song | Rounding Whole Numbers
With lyrics like the following, Numberock's rounding song has been declared to be pure mathematical poetry:
“The number to the right must be found:
Five or more? ROUND UP! Less than five? ROUND DOWN!”
You're students will definitely ask you to play this one again. All that is left to do is to smash that play button on our rounding numbers song, watch your students become more engaged than you ever thought possible, and, finally, credit yourself for the awesome job done!
Rounding Numbers 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!
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!
