How to Round Numbers

STEP 1:

Underline the digit in the place value noted

Round 63,125 to the thousands

STEP 2

Draw an arrow to the digit on the right of it

63,125

STEP 3

If that digit is less than 5, the underlined digit remains the same (this is called rounding down)

63,125

BUT

If that digit is 5 or more, the underlined digit goes up one(this is called rounding up)

63,125

Any digits to the right of the underlined number become “0”s

63,125
