What children learn in Level 6

Look at the 4s in 44,000. They're the same digit, but they're in different places.
The first 4 is in the ten thousands place, so it's worth 40,000. The second is in the thousands place, worth 4,000.
One place to the left is worth ten times as much. 40,000 is 10 times 4,000.
Atlanta has about 500,000 people, and Valdosta has about 50,000. The 5 in 500,000 is one place to the left, so Atlanta has about 10 times as many people!
Two places to the left is 10 times 10, or 100 times as much. 7,000 is 100 times 70.

Georgia's K-12 Mathematics Standards:

4.NR.1.2 — Recognize and show that a digit in one place has a value ten times greater than what it represents in the place to its right and extend this understanding to determine the value of a digit when it is shifted to the left or right, based on the relationship between multiplication and division.
