Solving Linear Inequalities
Students will solve and graph linear inequalities in one variable, understanding interval notation.
Key Questions
- Explain how solving inequalities differs from solving equations, particularly with multiplication/division by negative numbers.
- Analyze the meaning of an open vs. closed circle on a number line graph of an inequality.
- Compare interval notation to inequality notation for representing solution sets.

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.
