Option 1: Rounding

This week you will be working on mastering rounding. First, read over the steps to rounding. They are below:

1. Underline the number in the place value you want to round to.
2. Circle the number to the right of the underlined number.
- If the circled number is a 0,1,2,3, or 4, the underlined number stays the same.
- If the circled number is a 5,6,7,8, or 9, the underlined number increases by 1.
3. Change all of the numbers to the right of the underlined number to zeros.
