Key Concepts

  • Exponents
  • Base
  • Power of a Power Rule

Learning Objectives

  • Students will be able to identify the base and exponents in a power of a power expression.
  • Students will be able to apply the power of a power rule to simplify expressions.

Educator Instructions

  • Introduction (5 mins)
    Begin by reviewing the definition of an exponent. Briefly discuss what a base and an exponent represent. Ask students for examples of exponents they've encountered before.
  • Video Presentation (7 mins)
    Play the "Power of a Power | Exponent Rules | Math with Mr. J" video. Instruct students to take notes on the rule and the examples provided.
  • Guided Practice (10 mins)
    Work through example problems on the board, demonstrating the power of a power rule step-by-step. Start with simple examples like (x^2)^3 and gradually increase complexity. Relate the rule back to repeated multiplication to enhance understanding.
  • Independent Practice (10 mins)
    Provide students with a worksheet containing power of a power problems of varying difficulty. Circulate to provide assistance and answer questions. Encourage students to check their answers with each other after completing the worksheet.
  • Wrap-up and Assessment (8 mins)
    Review the key concepts and the power of a power rule. Administer the multiple choice and/or fill-in-the-blank quiz to assess understanding.

Interactive Exercises

  • Exponent Card Sort
    Create cards with expressions like (x^2)^4 and x^8. Have students match the equivalent expressions.

Discussion Questions

  • Why does the power of a power rule involve multiplication of exponents instead of addition?
  • Can you think of a real-world example where the power of a power rule might be useful?

Skills Developed

  • Applying exponent rules
  • Simplifying algebraic expressions
  • Problem-solving
