## Number & Operations in Base Ten – 4th Grade

**Generalize place value understanding for multi-digit whole numbers.**

Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right.

*For example, recognize that 700 ÷ 70 = 10 by applying concepts of place value and division*.

**Teacher Notes
**The teacher needs to understand the relationship between the base ten number system and place value. The teacher must be able to explain that the value of a digit changes depending on where it is located in a number.

Understanding how the value of a digit changes depending on where it is located in a number is essential. In a base ten system, multiplying or dividing a number by 10 changes the value of the digit by one whole place value position.
