1. Scientific Notation

2. 5 jumps right 9 jumps left Scientific Notation – a way to write very large or very small numbers. Examples When would people use scientific notation in real life? Examples: 6,320,000,000 0.000027 = =

3. 11 jumps left 4 jumps right 7 jumps left Large Numbers Small Numbers 59,000,000 140,000,000,000 0.000426 0.000009 = = = 6 jumps right =

7. Now it’s time to compare and order numbers written in scientific notation!

8. How to Compare/Order Numbers written in Scientific Notation: 1)Compare/Order the exponents 9.5 x 10 6 8.6 x 10 7 3.2 x 10 -2 4.1 x 10 -5 2)If the exponents are the same, compare/order the actual numbers 4.7 x 10 7 5.2 x 10 7 7.2 x 10 -5 8.1 x 10 -4

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