1. Lesson 6.9: Scientific Notation
Standards: NS 1.1, AF 2.1
Objectives: Write scientific notation.
Use scientific notation.

2. Objective - To use scientific notation to write very large or very small numbers.
Examples:
6,320,000,000 =
9 jumps =
5 jumps

3. Large Numbers (positive exponent)
59,000,000 =
7 jumps
140,000,000,000 =
11 jumps
Small Numbers (negative exponent) =
4 jumps =
6 jumps

4. Write using scientific notation. 1) 81,000 4) 0.00015
4 jumps
4 jumps
2) 1,396,000 5)
6 jumps
5 jumps
3) 80,000,000,000
10 jumps

5. Write each number in standard form.1) 4)

6. Multiplying Scientific numbers
(2.3 x 106)(5 x 103) =
Multiply the COEFFICIENTS
(2.3 x 5) = 11.5
Add the EXPONENTS = 109
Move decimal in final answer AND change exponent by 1.
11.5  x 1010

7. Comparing Numbers in Scientific Notation
Order the following from greatest to least.
middle
largest
smallest
