Hook: The Magic of Parabolas

---

Introduction:

Imagine you are at a theme park, standing in line for the latest roller coaster ride called “The Parabola.” The ride promises thrilling drops and steep climbs that mirror the shape of a quadratic function. Today, we’ll explore the world of quadratics, not only to understand their mathematical properties but also to appreciate their real-world applications, like designing those very roller coasters!

Visualisation:

Before we dive into the equations, let’s set the scene visually. Project a dramatic image of a roller coaster that features steep curves and loops. Next, ask your students:

• What shapes do you see?
• What mathematical principles do you think are behind the design of this roller coaster?

Interactive Questions:

Encourage a discussion by posing the following questions:

1. What do you think happens to the speed of a cart on a roller coaster at the highest peak?
2. Can you describe how you might predict where the cart will be at any point in its journey?

Transition to the Topic:

After eliciting responses, you can connect their ideas back to the topic of quadratics:

“Today, we will uncover the secrets of the quadratic function, represented by the equation (y = ax^2 + bx + c). Just like the roller coaster, understanding these functions can help us predict movement, growth, and even the trajectory of a ball in sports!”

Moving Forward:

From this exciting introduction, segue into exploring:

• The standard form of a quadratic equation.
• The significance of the coefficients (a), (b), and (c).
• Graphing methods and the iconic parabolic shape, including the vertex and axis of symmetry.

Encourage students to think about how these concepts relate to their personal experiences, perhaps by sharing stories of their own adventures on roller coasters, leading to a deeper connection with the mathematics behind them.

Conclusion:

By starting the lesson with a vivid, relatable scenario, you not only engage the students but also set the stage for an exciting exploration into the world of quadratics. Let’s buckle up and dive into the mathematics of curves!
