Year 12 Retrieval: Modulus Functions and Equations
Solving equations and inequalities involving the modulus function and interpreting their graphical representations.
Key Questions
- Evaluate the most efficient strategy for solving a modulus inequality, comparing algebraic case-analysis with graphical interpretation and justifying your choice.
- Analyse how modulus functions give rise to piecewise-defined integrands, and explain the adjustments required when evaluating definite integrals over such functions.
- Synthesise graphical and algebraic methods to solve a modulus equation involving an exponential or logarithmic expression, verifying that all solution branches have been captured.

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.
