Graphs of Modulus Functions
Students will apply reflections across the x-axis to quadratic graphs and sketch the resulting graphs.
Key Questions
- Explain how the piecewise definition of the modulus function determines which portions of y = f(x) are reflected to produce y = |f(x)|, and identify any new features introduced.
- Compare the graphs of y = |f(x)| and y = f(|x|) for a given function, analysing the distinct symmetry properties each transformation imposes.
- Evaluate how the modulus transformation affects the domain, range, and asymptotes of a rational or exponential function, and justify your conclusions using specific examples.

Planning templates for Mathematics
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.
