Frequently asked questions
What is the rule for rounding?
Look at the digit to the right of the place you are rounding to. If it is 5 or more, round up; if it is 4 or less, round down. 47 to the nearest ten is 50; 43 is 40.
Why does 5 round up?
It is a convention so that everyone rounds the same way. Scientists and banks sometimes round 5 to the nearest even number instead, but schools teach rounding up.
What grade learns rounding?
Third grade rounds to tens and hundreds; fourth grade rounds any multi-digit number to any place.
