Adding and Subtracting Rational Expressions
Finding common denominators and performing addition and subtraction of rational expressions.
Key Questions
- How does the search for a lowest common denominator change when dealing with variable expressions?
- Differentiate between the steps for adding/subtracting rational expressions and multiplying/dividing them.
- Critique a student's work to identify common errors in finding common denominators for rational expressions.

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.
