This is the common method that we use to measure a place value. As we know when a place value is greater than nine, that value carries over to the place to the left. With base ten each place value can have a minimum value of zero and a maximum value of nine. This basically defines how we carry out many different operations in math. The base ten system makes it pretty simple to convert between values of currency and decimal values. Since the concept is each place is a difference of ten, a difference of two places is a hundred value difference (10 x 10). To take it further, a difference of three places is a thousand value difference (10 x 10 x 10). The base ten system is just another name that is often used for the decimal number system. All the numbers in this number system are formed by combining tens or hundreds. If we look at the movement between each place value we will notice that it differs by tens.

The series of lessons and worksheets that are presented here help you understand the concept of the value of base ten within the place value system. These worksheets help students to practice identifying place values, regrouping numbers, breaking numbers apart, and more. Many questions use simple illustrations for grouping and calculating tens/ones.
