Relating Place Value and Multiplication by 10
In our base-10 number system, each place value is 10 times greater than the place to its immediate right. When you multiply a number by 10, you are making its value 10 times larger. This is represented by bundling groups of 10 units and moving them to the next higher place value. This 4th grade skill appears in Chapter 1 of Eureka Math Grade 4 (Place Value of Multi-Digit Whole Numbers) and lays the groundwork for more advanced mathematical reasoning in 5th grade.
Key Concepts
The value of each place is 10 times the value of the place to its right. This means bundling 10 units of a smaller place value creates 1 unit of the next larger place value. $$10 \times 1 \text{ thousand} = 1 \text{ ten thousand}$$ $$10 \times 1 \text{ ten thousand} = 1 \text{ hundred thousand}$$ $$10 \times 1 \text{ hundred thousand} = 1 \text{ million}$$.
