  4. Activator What if you had to tell someone to multiply the following number: 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 Do you think it will be an easier way to tell them?

  5. EQ: How do I use the properties of exponents to extend the meaning beyond counting number exponents? Standard: MCC8.EE.1 Know and apply the properties of integer exponents to generate equivalent numerical expressions.

  6. Exponents exponent power base

  7. The Laws of Exponents: Exponential and Expanded forms: The exponent of a power indicates how many times the base multiply itself. = 125 EXPONENTIAL FORM Standard Form Expanded Form

  8. The Laws of Exponents: • 1st Law: Product of a Power: • If the BASES are the SAME and… • If the operation between the bases is MULTIPLICATION • Then we KEEP THE BASE and ADD EXPONENTS.

  9. The Laws of Exponents: 1st Law: Product of a Power:

  10. We Do, You do… We Do: You Do:

  11. The Laws of Exponents: • 2ndLaw: Quotient of a Power: • If the BASES are the SAME and… • If the operation between the bases is DIVISION • Then we KEEP THE BASE and SUBTRACT EXPONENTS.

  12. The Laws of Exponents: 2nd Law: Quotient of a Power

  13. We Do, You do… We Do: You Do:

  14. Student Practic: White Boards • Students will complete practice problems over the 1st and 2nd Law of Exponents by competing in a two teams. • Students will have to work problems on the board as the teacher calls out each problem. • The team with the most points at the end of the game (20 mins) will be the winner!
