Finding Equations of Linear Lines
Students will derive the equation of a straight line given two points, a point and a gradient, or its intercepts.
Key Questions
- Evaluate the minimum amount of information needed to uniquely define a straight line.
- Design a strategy to find the equation of a line given only its x and y intercepts.
- Compare the most efficient method for finding a linear equation in different scenarios.

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.
