Transformations of Functions (Stretches)
Students will investigate how multiplying a function or its variable by a constant stretches or compresses its graph.
Key Questions
- Explain how a stretch parallel to the y-axis differs from a stretch parallel to the x-axis.
- Compare the visual effect of a stretch factor greater than 1 versus a stretch factor between 0 and 1.
- Design a sequence of transformations to map one function onto another.

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.
