Rational Root Theorem
Students will use the Rational Root Theorem to identify potential rational roots of polynomial equations.
Key Questions
- Explain how the Rational Root Theorem narrows down the search for polynomial roots.
- Analyze the relationship between the leading coefficient, constant term, and possible rational roots.
- Critique the limitations of the Rational Root Theorem in finding all types of roots.

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.
