Key Concepts

  • Hyperbola Equation (Horizontal and Vertical)
  • Center, Vertices, and Foci of a Hyperbola
  • Relationship between a, b, and c (c² = a² + b²)

Learning Objectives

  • Identify the equation of a hyperbola given its vertices and foci.
  • Determine the center, vertices, and foci of a hyperbola given its equation.
  • Distinguish between horizontal and vertical hyperbolas based on their equations.

Educator Instructions

  • Introduction (5 mins)
    Begin by reviewing the definition of a hyperbola and its key components (center, vertices, foci, asymptotes). Briefly discuss the difference between horizontal and vertical hyperbolas, building upon prior knowledge of conic sections.
  • Video Lecture (15 mins)
    Play the Kevinmathscience video: 'Hyperbola Equation Conic Sections'. Instruct students to take notes on the formulas for horizontal and vertical hyperbolas, and the relationship between the center, vertices, and foci.
  • Guided Practice (15 mins)
    Work through examples similar to those in the video, emphasizing the steps to identify the center, a, b, and c, and then plug those values into the appropriate hyperbola equation. Start with simpler examples and gradually increase complexity.
  • Independent Practice (10 mins)
    Assign practice problems where students determine the equation of a hyperbola given its vertices and foci. Encourage them to draw a sketch of the hyperbola to visualize the information.
  • Wrap-up and Assessment (5 mins)
    Summarize the key concepts learned. Administer the multiple choice quiz and fill in the blank quiz to assess understanding.

Interactive Exercises

  • Graphing Hyperbolas
    Use Desmos or a graphing calculator to graph hyperbolas given their equations. Students can manipulate the values of h, k, a, and b to see how they affect the graph.
  • Hyperbola Matching Game
    Create a matching game where students match hyperbola equations with their corresponding graphs or key features (center, vertices, foci).

Discussion Questions

  • How does the equation of a horizontal hyperbola differ from the equation of a vertical hyperbola?
  • What does the value of 'a' represent in the context of a hyperbola?
  • How does changing the values of a and b affect the shape of the hyperbola?

Skills Developed

  • Algebraic Manipulation
  • Problem-Solving
  • Visual Reasoning
