Equations of Straight Lines
Deriving and using various forms of linear equations (gradient-intercept, point-gradient, general form).
Key Questions
- Differentiate between the gradient-intercept form and the general form of a linear equation.
- Construct a linear equation given two points or a point and a gradient.
- Evaluate the most appropriate form of a linear equation for different problem types.

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.
