The Discriminant and Nature of Roots
Students will use the discriminant to determine the number and type of solutions (real/complex) for a quadratic equation.
Key Questions
- Explain how the value of the discriminant predicts the number of x-intercepts of a parabola.
- Differentiate between real and non-real (complex) solutions based on the discriminant's value.
- Analyze the graphical implications of a positive, zero, or negative discriminant.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
rubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
