POTD Use your place value chart to answer the following questions: 1,234,567 1. What is the value of the number in hundreds place? 2.What is the place of the 2? 3.What is the value of the 3? 4.Which number is in the thousands place?

3
The value of a digit is 10 times the value of the digit to its right. Place Value/Base 10

4
Let’s draw ten ones. What larger unit can I make? Tens ones 1 ten= 10 x 1 one “1 ten is 10 times as much as 1 one.”

5
Let’s draw ten 10s. What larger unit can I make? hundreds Tens ones 1 hundred= 10 x 1 ten “1 hundred is 10 times as much as 1 ten.”

6
Let’s draw ten hundreds. What larger unit can I make? Thousands hundreds Tens ones 1 thousand= 10 x 1 hundred “1 thousand is 10 times as much as 1 hundred.”

7
In the ones column the number “1” represents one cube. In the tens column the number “1” represents one group of ten. In the hundreds column the number “1” represents one group of a hundred. The “1” in the tens column represents ten times the number of cubes as the “1” in the ones column. The “1” in the hundreds column represents ten times the number of cubes as the “1” in the tens column. Hundreds Tens Ones

9
Why is 300 less than 3,000? Possible response: The 3 in the hundreds place is 10 times less than the 3 in the thousands place.

Examples

11
4 x 100 = 4004 x 10 =40 4 40 400 4 x 1 =4

12
300 3,000 3 x 1,000 = 3,000 3 x 100 =300

13
200 2,000 2 x 1,000 = 2,0002 x 100 = 200 Why is 200 less than 2,000?

14
What is the difference between the 3’s in the number 343? What is the difference between the 4’s in 43,478? Possible Response: The 3 in the ones place is 100x less than the 3 in hundreds place. (the opposite is also true)

15
Guided Practice/Independent ThousandsHundredsTensOnes 1. Label the place value charts. Fill in the blanks to make the following statements true. Draw circles in the place value chart to show how you got your answer, using arrows to show any bundling. a. 10 × 3 ones = ________ ones = __________
