9 Steps to Round a Number: STEPS: 1.Underline the place you are rounding to. 2.Circle the number to the right. 3.If the number to the right is 0, 1, 2, 3, or 4, then the underlined number stays the same. 4.If the number to the right is 5, 6, 7, 8, or 9, then the underlined number needs to go up 1 more number. 5.Every number to the right of the underlined number becomes a zero. Copyright © 2009 Kelly Mott Round to the nearest thousand: 2,672 Hint for the Circled Number: 4 or less just ignore. 5 or more, add 1 more.
