Our Target:
By the end of today's lesson, you should be able to...
• Read and write large numbers in standard, expanded, and
number-and-word notations
• Express the value of digits in a number

Standard Notation
•
Each place is 10 times the place to its right
•
each period, or group, is divided into ones, tens,
hundreds
•
Each period is separated by a comma
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ h t o h t o h t o h t o h t o

95,000,000,000,000
Let's take a closer look...
What are some patterns that you see above?
•
each place is ________ the value to its right
• each group is divided into 3 places
•
each group is separated by a comma
What number would be... •
10 times greater than 95,000,000,000? •
1/10 times as great as 95,000,000,000?

Create a place value chart on your whiteboard.
Write the number as the teacher reads it to you.

Expanded Notation
•
A number is written as the sum of the values of
its digits
345 = 300 + 40 + 5
12
(1 * 10,000) (9 * 1,000) (6*100) (3*10) (6*1)

NumberandWord Notation
Significant digits followed by a word for the place value
of the largest period
63,800,000 = 63,800,000 = 63.8 million
1. Choose the largest period group 2. Replace the comma with a
decimal 3. Write down any other digits to the right of the
decimal 4. Write the word for the largest period
