What children learn in Level 32
- Welcome to Division Depot! Atlanta has about 500,000 people. Valdosta has about 50,000. Atlanta has about 10 times as many people.
- Dividing by 10 undoes multiplying by 10, so each digit moves one place to the right. The 5 hundred thousands become 5 ten thousands.
- Dividing by 100 moves each digit two places to the right: 4,700 divided by 100 is 47.
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.
