Key Concepts

  • Cubing a number (raising to the power of 3)
  • Cube root as the inverse operation of cubing
  • Perfect cubes (results of cubing integers)

Learning Objectives

  • Students will be able to define and explain the concept of cubing a number.
  • Students will be able to identify the first 10 perfect cubes.
  • Students will be able to calculate the cube root of the first 10 perfect cubes.

Educator Instructions

  • Introduction (5 mins)
    Begin by introducing the concept of cubes and cube roots. Explain that this lesson will cover the first 10 perfect cubes. Briefly review the concept of squaring a number and square roots as a connection.
  • Video Viewing (10 mins)
    Play the "Perfect Cubes and Cube Roots (1-10) | The First 10 Perfect Cubes and Cube Roots | Math with Mr. J" video. Encourage students to take notes on the perfect cubes and their corresponding cube roots.
  • Guided Practice (10 mins)
    Work through examples similar to those in the video on the board. Start with 1 cubed, then move to 2 cubed, etc. Then have students solve for the cube root of 1, 8, etc. Emphasize the relationship between cubing and finding cube roots. Use visual aids or manipulatives if available.
  • Independent Practice (10 mins)
    Provide students with a worksheet containing problems where they need to calculate perfect cubes and cube roots. Problems should range from 1 cubed to 10 cubed. Also include finding the cube root of 1, 8, 27, 64, 125, 216, 343, 512, 729, and 1000.
  • Review and Wrap-up (5 mins)
    Review the answers to the worksheet problems. Address any remaining questions or misconceptions. Reiterate the importance of memorizing these perfect cubes and cube roots for future math concepts.

Interactive Exercises

  • Cube Root Matching Game
    Create matching cards with perfect cubes on one set of cards and their cube roots on another. Students match the perfect cube with its corresponding cube root.
  • Online Cube Root Calculator Exploration
    Have students use an online cube root calculator to explore larger numbers and verify their answers from the independent practice.
