To round any number, follow these rules:




Underline the place value you are rounding to.
Circle the digit to the right of the underlined digit.
If the number is : 0,1,2,3 or 4 the digit stays the same.
If the circled number is: 5,6,7,8 or 9 the underlined digit goes up
by 1.
 The circled digit and all digits to the right become 0.
Rounding examples:
