Introduce the topic, highlight the importance of understanding the discriminant for determining the nature of roots in a quadratic equation. Emphasize that today's session is interactive and encourage student participation from the start.

Define the discriminant in simple terms. Go over the formula b² - 4ac and explain what it indicates regarding the number and type of solutions (roots). Encourage students to share any previous encounters with similar concepts.

Present specific examples that clearly show each scenario: a positive, zero, and negative discriminant. Use visual aids from the interactive examples material to connect equations to their graphs.

Discuss some challenges that may arise when teaching this concept. Mention the abstract nature of the discriminant for young learners, and suggest strategies like interactive questioning and visualizations. Explain the benefits of learning the discriminant before the full quadratic formula.

Summarize today's content and encourage student reflection. Invite questions and provide additional resources, referring back to the visual material on quadratic graphs for further exploration.
