Grade 4 Math · World 1: Place Value Peaks · Level 5
Ten Times as Much
Each place is worth ten times the place to its right.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 5
- 10 ones make a ten. 10 tens make a hundred. 10 hundreds make a thousand.
- The pattern keeps going! 10 thousands make 10,000, and 10 ten thousands make 100,000.
- So each place is worth ten times the place to its right. When the 1 moves one place to the left, it's worth ten times as much.
- It works for any digit. Ten times as much as 400 is 4,000. The 4 moves from the hundreds place to the thousands place.
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.
