How to Round Values Based on Place Value - Sometimes you need rounding off of numbers to make them simpler and easier to understand. Rounding off is also used for eliminating the decimal points in the number. This tutorial discusses number place values, the mathematical rules of rounding, and gives plenty of examples. Each digit in a number has a position called its place value. Look at the image below. To the left of the decimal point are integers, and we reference these place values as ones, tens, hundreds, thousands, and so on. To the right of the decimal point are decimals, referenced as tenths, hundredths, thousandths, etc. As we move from right to left in a number, each place value is ten times larger than the place value to its right. These worksheets and lessons reinforce the concept of place value and we have students learn how to round to fixed places.

#### Homework Sheets

1. Find the underlined place value. 2. Complete the expanded form for each number in standard form. 3. Compare the place values.

- Place Homework 1 - Multiples of 100 always have zeroes in the ones and tens place.
- Expanded Homework 2 - If the hundred place number is 5 or higher, we round to the higher number.
- Compare Homework 3 - Multiples of 1000 always have zeroes in the ones, tens, and hundreds place.

#### Practice Worksheets

I receive a great deal of positive feedback on these sheets. Most teachers love the diverse questioning technique.

- Practice 1 - If the hundred place number is 4 or less, we round down.
- Practice 2 - Determine the place value of the underlined number.
- Practice 3 - The best thing to do is to break the numbers into all the place values.
