1. Place Value by Mrs. Sherwood
Let’s think about what the position of the numeral means in a number, practice reading large numbers, write numbers in expanded notation (expanded form), and tell the place and the value of a numeral in any position in a number. Let’s get started!

2. Periods
Billions
Millions
Thousands
Ones H T O 5, 4 9, 2 1 6, 7

3. Reading Large Numbers
When you see a large number to be read, start at the
right hand side and think: ones, thousands, millions,
billions. Then read the digits in each period and say
the name of the period when you get to the comma.
Try this one:
4,569,092,067

4. Let’s try a few more.
43,609,087,490
189,987,000,223
5,208,321,000

5. Expanded Notation
When using expanded notation, we write the value of each digit. For example, a 6 in the ten billion place is worth 60,000,000,000.
Let’s try it with this number:
4,590,432,721 = 4,000,000, ,000, ,000, , , ,

6. Write these numbers in expanded form in your binder. 7,456,284,009
Now you try!
Write these numbers in
expanded form in your
binder.
7,456,284,009
856,942,304
77,098,341,119

7. Check your work!
7,456,284,009 = 7,000,000,000 +
400,000,000 +
50,000,000 +
6,000,000 +
200,000 +
80,000 +
4,000 + 9

8. 856,942,304
= 800,000,000 +
50,000,000 +
6,000,000 +
900,000 +
40,000 +
2,000 +
300 + 4

9. 77,098,341,119
70,000,000,000 +
7,000,000,000 +
90,000,000 +
8,000,000 +
300,000 +
40,000 +
1,000 +
100 +
10 + 9

10. Place and Value
Can you tell the name of the place
and the value of the digit?
For example: In the number
4,234,789 the red 4 is in the
thousands place and it its value
is 4,000.

11. Now you try! Name the place and value of each red digit. 405,237,694
The five is in the millions place and its value
is 5,000,000.
35,897,479,502
The nine is in the ten millions place and its
value is 90,000,000.

12. You did it!
