Rounding Numbers means to shorten a number based on rounding rules
Rounding is useful for estimating numbers
Remember the TWO key rounding rules:
5 and higher, ROUND UP
4 and below, ROUND DOWN
You apply rounding rules to the digit to the right of what you are rounding
For example, If I am rounding to hundreds, I will look at the tens digit
Remember the rhyme:
“Knock, knock on the door, round up if I am higher than four”
