Lesson
How can we compare the values of large multidigit whole numbers?
If someone asked you, "Which number is larger? 15 or 8?" You could easily tell them that 15 is the larger number, and 8 the smaller number. But what if the numbers are much larger? A bank manager might be asked to compare the values of two homes for sale. If one home costs $480,000 and the other $478,832, which house costs more? In this lesson, we will show you two strategies to easily and accurately compare multidigit whole numbers. 
Using Exponents to show the Powers of Ten
In Math, we have these cool symbols called "exponents" to help us write large numbers like 1,000,000 a little more efficiently. You have probably seen these tiny numbers on the corner of numbers before: The exponent is the tiny red number above the ten above. It tells you how many times to multiply the number ten. For example, 10 to the power of two (above) is the same as 10 x 10, which equals 100.
You will use these exponents to help you organize complex and long numbers in middle school, high school and beyond!
