The Mission: To be able to write numbers in expanded notation and scientific
notation.
The Plan: To follow the directions of the Web Quest and complete the Web Quest
packet
The Rules:
1. All directions are written in RED
2. You must follow ALL directions given. DO NOT SKIP any directions. If you
are asked to watch a video, you must watch the ENTIRE video before moving
on.

worksheet.
1. Complete questions 1-10 on p. 214 in your Web Quest packet.
***Remember…Calculations with exponents are done BEFORE
other factors are multiplied.
2. Then, read about scientific notation on p. 214 in your packet.
3. Record the definition for “scientific notation” on your vocabulary list.
4. Complete questions 11-14 on p. 214 in your Web Quest packet.

To write a number in EXPANDED NOTATION, multiply each digit in
the number by the value of it’s place.
Example:
3,269
The 3 is in the 1,000’s place.
The 2 is in the 100’s place.
The 6 is in the 10’s place.
The 9 is in the 1’s place.
3 * 1,000
2 * 100
6 * 10
9*1
So, the EXPANDED NOTATION looks like this:
(3 * 1,000) + (2 * 100) + (6 * 10) + (9 * 1)
OR
3000
+
200
+
60
+
9

Now copy the definition below for expanded notation into your
vocabulary list.
expanded notation- a way of writing a number as
the sum of the values of each digit. (Ex. 356 is 300
+ 50 + 6 in expanded notation)

Let’s look at an EXAMPLE:
Let’s write 52,000 in scientific notation.
-Write the first number in the one’s place
followed by a decimal and any other NONZERO numbers
- 5.2
-Next, multiply that number by 10
-5.2 x 10
-Finally, count how many places you moved
the decimal. This is your power of ten
exponent.
- 5.2 x 104
63,000
=
412,000
=
6.3 x 104
4.12 x 105
Let’s try one more!
1,236,000
=
How do you feel?
Great!
1.236 x 106
